A cylindrical water vessel made of metal with rounded edges. Sent by Gulpax as an expedition into the Frozen Expanse, it became frozen beneath the ice in a local lake. The entire crew is made up of Constructs.

I always wondered what happened to the first team of Contructs I sent to chart the Frozen Expanse. It was quite a shock to discover my diving boat after all these years, trapped beneath the lake! - Gulpax's Journal (GS-Journal)

“Gulpax sent us on a scouting expedition into the Frozen Expanse, but our vessel became trapped in the ice.” - Beta-Three-Seven - The Frozen Expanse (GS-ADV6)

Walking across the frozen lake, you notice a metal shaft sticking up from the ice. It is attached to an unusual metal vehicle, frozen beneath the ice.
