Wilson, Zmerr talking about the jungle refers to when he lived in it as a child.

[quote=Zmerr]She led him into the jungle, telling him that there was an abandoned city. It had been a trap. She sneaked away when he wasn't paying attention and left him to his own devices. He wandered the jungle for an unmeasured amount of time. He finally found his way out and sought refuge. During the time he'd spent in the jungle, the world had been "purged" of non-humans and he was forced to evacuate. He found a deserted island and made a home for himself among the ruins.[/quote]
