Ball of Light

After waking up, Steve doesn't know where he is. Heck, he doesn't know what he is. Despite his spotty memory, he's pretty sure he didn't used to be a floating ball of light. He's also certain that he's not originally from this dangerous fantasy world...maybe. Okay, fairly certain. To make things stranger, he seems to be involved in something big, something magical...a game. Who was he before? Will his memories come back? Why does he have an assistant explaining the game's rules to him?He can evolve? There's a countdown timer? One thing Steve does know is that he needs to figure out what's going on fast, and if he is playing a game, even a deadly one, he plans to win.
