Aced

Foreteller Aced is a Keyblade Master who appears in Kingdom Hearts χ. He is the leader of the Ursus Union.

Before Kingdom Hearts χ
According to Chirithy, Aced was originally one of the six apprentices of his creator, the "Master of Masters". He was assigned his name by the Master, and like the other four chosen to become Foretellers, he received a tome from the Book of Prophecies. Afterward, he established the Ursus Union to battle the darkness while using his tome to draw power from the future in the form of s, in an attempt to avert the Keyblade War prophesied in the Book.

Kingdom Hearts χ
Shortly after the Player arrives in Daybreak Town, Foreteller Aced assigns a Chirithy to assist them and explain the current situation.

In Kingdom Hearts χ, the Player is attacked by a Darkside upon arrival, but Aced shows up in person to chase the Darkside back through its Corridor of Darkness, leaving behind the Chirithy.

After the Player learns to wield the Keyblade with help from Chirithy, Aced appears from a lane between. He explains the need to defeat Heartless and collect Lux, while noting that there is help in the form of their Union; as if to illustrate the point, a Darkside appears but is quickly dispatched by arriving members of the Union. Before leaving once again, Aced warns that some are seeking to collect the Lux out of greed rather than peace, and entreats the Player to help root out the darkness.

As the Player continues to defeat Heartless and retrieve Lux, their Chirithy makes regular reports on their progress to Aced, who occasionally assigns the Player tests of skill in response.

Following the demise of Chirithy (2), Aced informs Chirithy that despite the Unions' best efforts, darkness continues to grow in power, leading Chirithy to speculate that there is a traitor among the Foretellers.

Some time later, Chirithy comes to the Player with a new assignment from Aced: they must hunt down Heartless within the Corridors of Darkness themselves, with only a set of Beads of Light to survive exposure to the darkness. After the Player successfully completes this task, Chirithy reports it to Aced, but questions the wisdom of assigning such a dangerous mission. Aced explains that the darkness continues to spread, unabated, and that the Unions must grow as much as possible and develop a resistance to the darkness in order to survive.

After a long day of pursuing Minute Bomb Heartless, Player returns home for some much needed rest. That night, while Player sleeps, they dream of the Clock Tower, where they see all five Foretellers meeting with someone in a Black Coat, Unknown. Before Player can investigate however, they are surrounded by Darkness and pulled out of the dream; finding Chirithy to be sitting in the room with them when they wake. Chirithy asks what had happened, as it looked as though Player was having a pretty bad nightmare, when Player confirms this, Chirithy advises them to go back to sleep. When Player is sleeping once again, Chirithy turns to the window and asks if he’s right to assume that Chirithy (3) had been the one to get in the way. Chirithy (3) materializes and asks if Chirithy was showing The Player a dream and what it was up to. Coldly, Chirithy claims that his interests are the exact opposite of Chirithy (3). Chirithy (3) sighs and asks if that means that they’ll become enemies before disappearing again. Turning to Player, Chirithy asks itself whether or not it will be able to protect them.

Returning from their mission at Beast's Castle, an exhausted Player and Chirithy encounter another Keyblade wielder named Skuld, who wonders why the Unions are competing for the collection of Light when all the Unions have similar goals, reasoning that at some point people sought to outdo one another and that may have changed their goals ultimately. Abruptly, Skuld asks if she’s right to assume that Player knows Ephemera – shocking both Player and Chirithy – though Skuld explains that she knew Ephemera because they were from the same party. Continuing, Skuld explains that Ephemera had become a Keyblade wielder not long ago, and recently he’d left their party. Skuld admits that the next part is the most important, revealing that Ephemera has since visited her in her dreams and instructed her to help Player. When Chirithy asks why Ephemera would ask her to do such a thing, Skuld admits that she doesn’t know, though ever since Ephemera disappeared she’s felt as though she’s passed by him a hundred times – though he’s never greeted her, and she’s unsure why he’s appearing to her through her dreams; so she’s not even sure why she’d meant to work with Player. Ultimately she’d sought out Player in hopes that they might know something. Player then explains to Skuld that Ephemera’s appeared to them through their dreams as well. Happy to be finally getting somewhere, Skuld asks what Ephemera said and what kind of dream he’d appeared in. When Player explains the dream to Skuld, Skuld is intrigued by the fact that Ephemera had said that he’d be waiting for Player. Skuld then suggests that they return to the place Player went to with Ephemera once more, though Chirithy says that they can’t – as Master Ava had barred them from doing so. However, Skuld suggests that this is because there’s something there; believing that the reason Ephemera wanted her to work alongside Player likely has something to do with that. Skuld then mentions that there’s something else as well, only to be interrupted by a large crashing. Realizing that the sound came from nearby, Skuld summons her Keyblade and suggests that they investigate, with Player and Chirithy following close behind. Skuld, Player and Chirithy are brought to a stop when they see that the source of the crashing was in fact Master Invi and the Ursus Foreteller, Master Aced, battling across the rooftops of Daybreak Town. Skuld questions why the Foretellers are fighting one another, stating that it seems as though Ephemera was right; confusing Player and Chirithy. Skuld reveals that what she was going to say earlier was actually something that Ephemera told her in her dreams; that the end of the world was drawing near. Chirithy asks what Skuld means, and while she doesn’t know, she does remark on how the end always comes suddenly and without warning – similarly to how Ephemera disappeared.

After witnessing Master Invi and Master Aced's battle and encountering the Black Garment Heartless and Nightmare Chirithy, Player and Skuld continue to the waterways where Player had last seen Ephemera. Skuld asks for confirmation that this is where Player had last seen Ephemera - admitting that she's sure that there's something secret ahead. Before Player and Skuld can continue however, Chirithy blocks their path and asks if they truly intend to keep going even with everything that they'd just seen, admitting that he has an awful feeling about all of this; looking to his feet while Player attempts to comfort him. Skuld asks if she's right to assume that Chirithy knows the layout of the Clock Tower's internal structure, which Chirithy confirms, only for Skuld to order him to lead them onward. Relenting, Chirithy agrees to Skuld's request, reminding Skuld and Player that going further into the Clock Tower really is forbidden, so they have to come right back after a quick peek inside; which Skuld promises to do. As the three reach the room from Player's dream, Skuld asks where they are, and Chirithy explains that it is the last room - the Foretellers' room - prompting Skuld to question whether or not Ephemera made it that far. Given the situation, Chirithy mentions how, as they could see, there's no one there, and since they are not going to mess around with the things left in the room, it's time for them to go back as promised; stressing how they'd be in serious trouble if anyone found them up there. Skuld reluctantly agrees with Chirithy before taking another quick look around to be sure that there's really nothing up there, admitting that it feels as though they have been side-stepped, causing her to wonder what the dream with Ephemera really meant.

Just then, a voice comes from behind the group, as Master Invi ventures in from the shadows and asks what Player and Skuld think they are doing. Skuld asks Invi to excuse them, as they are looking for a friend of theirs. Master Invi simply asks how Player and Skuld could've possibly gotten in there if Chirithy was accompanying them - only for Chirithy to apologize for bringing them. Walking past Player, Invi reveals that there was another trespasser a few days before, wondering if they were a friend of theirs, which Player confirms. Skuld then asks if Invi knows Ephemera, prompting Invi to elaborate that Ephemera belonged to a Union which was in direct conflict with their own goals as a Union, suggesting that Ephemera must have gotten close to Player and Skuld in order to gather information about their Union. Coldly, Invi states that there was no way they would be seeing Ephemera ever again. Skuld, realizing what Invi is getting at, hastens to admit to herself that Invi had gotten rid of Ephemera. Invi confirms that he'd had Ephemera disappear, prompting shock and concern from Player, Skuld and Chirithy. Skuld insists that Invi won't get away with this, only for Invi to ask what Skuld thinks she's going to do about it. Chirithy then motions to stop Skuld, telling her that she can't and informing Invi that it's his fault and that he is the one responsible for everything that's happened, begging Invi to forgive Player and Skuld.

Player then steps out in front of Chirithy, looking to Invi and stating that, until today, they'd devoted themselves to their Union, to gathering Light in order to save the world and they had even competed against fellow Keyblade wielders that they think of as friends. Originally, they had thought that it was just what had to be done in order to save the world, and so they had tried not to dwell on what it meant, but at the same time someone had asked him that same simple question ("What are you going to do about it?") and that person was none other than Ephemera. Player admits that their encounter with Ephemera was brief, and that Ephemera had even broken a promise with Player - so their memories of Ephemera aren't all good - but they are huge and important to their heart. Player continues, saying that their sure it's because Ephemera was his friend, and that even if these feelings of anger and sadness signify Darkness, simply pushing them away is impossible. Player states that even if it came to crossing their Keyblade against Master Invi, they don't think they'd come away from it with any kind of peace. Perhaps it'd mean they would disappear as well, yet their sure that if Ephemera were there he would do the same. Preparing his stance for battle, Player beckons Master Invi forward into battle, prompting Invi to summon his Keyblade and launch herself into battle against Player.

Despite putting up a good fight against Master Invi, Player is easily defeated. Following the battle, Player is engulfed in a blinding light, which fades to reveal that they are back in the waterways alongside Skuld and Chirithy. Master Invi tells Player that they'd avoided being swallowed by their anger and sadness, and that they'd fought well.

Following Player's defeat, The Foreteller then radiates with light and reveals themselves to have actually been Master Ava the entire time, having generated the illusion of the Foreteller and the Clock Tower in order to test Player and Skuld's Hearts. -->
