Ziz was trapped in a computer at the Limbo Public Library for 8 years, 3 months, 14 days, 41 minutes, and 18 seconds.
Ziz was released from the computer by Silas Otwell and placed in his phone and brought to the Dorms where he immediately entered a Coma. Ziz got Kilo Errer's attention and was swapped to his phone. This made others in The Underdead mad so Kilo took Ziz to the Lucky Night to be away from everyone.
Later, due to problems within the Underdead, Ziz left Kilo's phone, uploading themself somewhere.
