Official Bio[edit]

"WAZZUP!! It's your worldwide Rat Idol --- Hakos Baelz!"

Chaos. Mayhem. Entropy..... All in the form of a cute little rat.

She is a performer looking for her next stage. Occassionally she will get swept up in her own storm, but thats just part of the fun.


A member of the Council and the very concept of Chaos, birthed by the world, itself.

The Gods appointed her Chairperson of the Council, but she mostly takes a hands-off approach as she has yet to accept the decision, much like her fellow members. That said, all of them have no intention of contending; instead to obey.

Her mouse-like appearance has deceived many a fool who fails to realize that mice are the harbingers of chaos.

Also of note is her wild smile, which she often flashes in her frequent romps.

Chaos is confusion and disarray, it is fortune and tragedy, and it is freedom from all the logic and inherent nature of life.

She believes that rules are not the be-all and end-all, which is why she has come to break them all.

Watching the aftermath is her greatest joy, and so she remains a bystander to the destruction caused by mayhem.

Streaming Information[edit]
