@sorvani At this point, we don't really know what the dungeon wants or will do in the future, so presuming the dungeon is going to provide food due to some altruistic nature would be a potential folly. For all we know, the dungeon could be aiming to make people reliant on them, while it harvests the souls and humanity of delvers and maybe even takes a bit with every bite of food.
Though that's one thing that's said about science and scientists... they are too focused on if it can be done and don't always stop and ask themselves whether it should be done.
Regardless, I'm sure there will be hijinks and more work for poor Naruse.
