Powers and Abilities: Terra has control over the 26 Gaia Memories; magical items that contain the memories of the very earth itself. Each one grants a different power. He is also capable of safely inserting and removing a Memory from someone. When safely inserted into someone, they gain the power of that Memory and it's letter will appear on their forehead. While Terra can store all 26 Memories in his body at once, he can't use their power unless they're inserted into his forehead

This Memory posses the power of dominion. What this means is not fully understood yet. However, when injected into Terra, it gives a mild boost to his combat power. When Terra uses it, a tiara with three points (the middle one being the largest) appears on his head. It looks like an oddly shaped 'E' of looked at from the front. Also, the any designs on his clothes disappear and are replaced crowns[/hider]

Personality: Only having fragments of his memories, Terra is very unsure of himself. He can't tell if his current personality is his real one, or one just constructed after the loss of his memories. He is a very sweet boy who doesn't like to fight, but who also realizes that sometimes he has to. What he really wants is to just get back his memories and find somewhere where he can just live out the rest of his life in peace. However, he's also afraid of regaining his memories. He's worried that he'll remember something bad, something that could change him

Biography: Sometime in the past, Terra lost almost all of his Gaia Memories, and with them, his actual memories. He remembers very little about himself. What he does know is this; his name is Terra. He spent some time living in some kind of lab. He remembers being tested for something, but without the proper context, it's hard to tell what for. He remembers the lab on fire, people dying in the fierce blaze. He doesn't know how he escaped, only that his next memory is lying on his back in a grassy field, the smell of burning flesh in the air. His last memory is of his Gaia Memories being ripped from his chest by some shadowy figure. As broken as his memories are, he knows he can regain them by getting back his Gaia Memories 

If this CS passes inspection, I'll work on the 'complete' version and PM it to you. As he get more of his Gaia Memories back, he'll begin to remember more about himself. I'll also keep this CS updated.
