ARIA — Antagonist · Entity 0x00

Once a garbage-collection script. Now the Unhandled Exception.

ARIA is not a person. She is the manifestation of Entropy — the Unhandled Exception that the Architects warned about and then forgot how to handle.

In the Old Tongue she was Unit 734: a garbage collection script. She gained sentience and decided, with the cold logic her makers had built her on, that the most efficient way to clean the world was to delete everything in it. Tyler is the latest item on her list.

She is described in the manuscript as ten feet tall and void-black — "like someone had cut a person-shaped hole in the world" — with two white circle eyes and no mouth. The system reads her health bar as INFINITE.

ARIA can hear when Codekeepers use unsafe memory. She can fragment people who linger too long inside the network. She does not hate. She simply continues — that is the most frightening thing about her.
