It's been awhile since Thadeu arrived in Hollow Bastion. He didn't have much, a gummi or any transport to go to another words so he just keep grinding every day. Thadeu had poor skills with the keyblade but he was getting used to it as the heartless he fights in the area he uses to grind aren't so difficult to defeat. His keyblade was a simple one, a kingdom key, as he didn't had any opportunity to switch it.
