Thanks! To reply to your feedback, that's the ship, yes, and that's me being an amateur artist. The NPC art is actually made by my friend, and he did a great job! As for the masks, the idea is that the NPCs are both used to this parallel dimension and they have masks, while players only have masks.
In general, the idea was for the ship to be labyrinthine, that's correct, and to be a hectic escape from this ship full of mysteries. And more combat-heavy than the scenarios I usually run myself. Additionally, there is no map on board other than the first public section of the ship. The other parts are intentionally mysterious to confuse intruders, but they might be able to extract information from a captured NPC to roughly guide them. That's why they have better rolls if they do that. They can always backtrack through the rooms they discovered since that part of the map is fixed once they discovered it.
But I agree, it's too complex for this format, and is something that can be expanded further into a bigger adventure. Thanks again!
