With no obvious threat nearby, the party decides to hunker down in the supply room for a chance to rest.
Chongo, Keoni, and Anar, working together, are able to push the water barrels over in front of the double doors. The group then piles the barrels up with some dirty wooden planks that they find stacked in one of the cubbies. When the work is completed, the doors are blocked nicely. A concerted effort could surely still breach the doorway, but the junk in the way should at least slow the intruder down, and give a noisy warning to boot.
The group decides to set up a rotating watch to allow the spellcasters the opportunity to recover their magic: Bael and Col together to start, then passing the duty to Keoni, then Chongo, and finally Anar and Kalen together at the end. With this decided upon, everyone settles in and tries to get some sleep.
Sleep doesn't come easy on the cold, stone floor, and an annoying dripping sound echoes from somewhere, but eventually slumber does come. Some time during Keoni's watch, the young shaman thinks he might hear something moving from the other side of the doors, but the noise stops before he can be certain, and it doesn't happen again.
Finally, after an extremely uncomfortable night, the party rouses. Muscles are sore and stiff, and bellies hungry, but the rest has accomplished its purpose. The group discusses what to do next as they remove their makeshift barrier from the door.
(Spells regained for all. Chongo raised to 14/14 hp)
