Akula

The Akula is an enormous metallic submarine the size of a small carrier, embedded nose-first into an underwater necropolis and functioning as a massive pump sucking in ocean water through its torpedo tubes. Its sail has been violently torn away. The flooded interior features tight warm corridors leading to a once-opulent bridge blending sci-fi command center with decaying Victorian luxury, now ruined by mold, rust, and flooding, with a huge porthole overlooking the deep sea.

The Akula first appears in book 4 of the Dungeon Crawler Carl series as an enormous metallic submarine lodged in an underwater necropolis. Serving as a massive pump, it draws ocean water through its torpedo tubes, its sail torn away and interior flooded with decay. This location showcases the evolving dungeon environments, transitioning from surface horrors to deep-sea mechanical ruins blending advanced technology with opulent decay.
