Bygone Fury

Bygone Fury is a boss in Detriment, encountered in the final level of Stewpit City, SC-B.

Encounter
After meeting up with Darrell, Herb and Peemb at the exit door in SC-5, the Player proceeds to place down the ankh on a strange pedstal in order to open the exit, unaware of it being a trap. After heading to a gated area, the four encounter Vance at a supposed location for the crystallite beaconpoint. Vance congratulates them for reaching him, while pulling out the player's ankh that was previously placed, before slamming it right on the ritual and running away. The sky becomes dark red, and Bygone Fury is summoned out of the ritual.
