Located in the Arcazion Pit, the cavern walls are carved with runes. The runes are painted with a green liquid and bathe the area in an eerie light. Blue flowers can be seen sprouting from cracks in the stones.
In the center of the cavern is an iron pump handle. The pump draws green liqued, looking much the same as that found in the Scrying Pool. Pipes lead to an opening in the leg of the Colossus.
The liquid can provide power to the Colossus. It is necessary for Gulpax's creation to fully automate.
“We have power! Power from the pit! With our tanks full, we already have one foot in the other world!” - Gulpax - The Arcazion Pit (GS-ADV7)
Upon entering the cavern, you discover a group of four Flayers. Together, they are working the long iron pump handle, drawing the green liquid from deep within the pit and redirecting it to the leg of the Colossus.
Depending on how quickly you discovered this site, a battle may rage throughout the cavern. Your earlier choices will determine your allies and the side you take. The outcome will determine if the Colossus gains full automation or not.
