Treasure Trove

The Treasure Trove (ロックスプレンダー) is a Keyblade that can be wielded by Terra, Ventus, and Aqua in Kingdom Hearts Birth by Sleep.

Design
The Treasure Trove's overall design is modeled after the crystal mines in the Dwarf Woodlands. The handle is brown and seemingly made of wood. The guard is circular and decorated by seven crystals, three white ones, two yellow, and two blue. The base of the blade is adorned by a black minecart filled to the brim with crystals in various shades of blue and yellow. The blade is made up of a short mine track with four crooked planks nailed onto it. A small pickaxe is attached to the head of the Keyblade in the same manner as the planks, forming the Keyblade's teeth. The Keychain is a beige cord that connects to the token, a red jewel.

A "treasure trove" is a phrase that refers to finding a hidden treasure, which reflects the gems the Seven Dwarfs mine. The Keyblade's Japanese name holds a similar meaning, with "splendor" meaning "great luster or brilliance". The full name, "Rock Splendor", references the luster of gemstones.
