Chaos Portal (NPC)

Yup.. It's a door. A locked door.
The final hurdle in your way, one last key to obtain.
Face Escherion if you dare, first you must avoid pain.
Win the battle, get the key, only then entrance you will gain.

- Relativity's Quests
- Proceed - Plays the 'The Runix Cube' cutscene

Location: Relativity
Note: Disappears after proceeding to the portal.
