Tense Thriller & Horror ⚑ 12 quests

Submarine

Every seal matters

Azuralis survives beneath crushing pressure, where every sealed door and every oxygen line matters. What first looks like routine sabotage becomes a plot to break the colony from within, setting engineers, abyssal clans, and security forces against one another while something vast stirs in the trench below. To save the domes, you must find the hand guiding the collapse.
