u/Bislack

A colossal creature, locked in a chamber with one way in and only one way out (to go on and continue her mission). The door we came in was closed, and it took us quite an effort to open it. The exit door was sealed shut by a mechanism that clicked only when we put down the gigantic aberration.

How did she go through it ? Did she go around ? Because as far as I remember there was no way around the ravines.
