That night, the desert gets punishingly cold, and the group huddles around what little they've brought with them that burns before falling asleep, huddled together under their cloaks.
Garn snores, to no one's particular surprise, and Maugra has a hard time sleeping because of it. She awakes in the pre-dawn gloom, ready to elbow him again -- and no longer being particularly diplomatic about it, this time -- when she realizes the noise is something else.
Blinking, she spies a large mechanical pump, banging and grinding away. She walks across the sand toward it, and when she hears, through the tulmult, the sound of liquid, she begins to run. A familiar stone bucket, which she had to fill at a similar pump in the Temple of Teun as a novitiate with pure clean water -- which had meant, in turn, learning how the pump worked, turning it off, disassembling it, cleaning it and reassembling it first -- sits full of water beneath a spigot.
Maugra drops to her knees, and plunges her hands into the bucket. The icy cold water pools in her hands, but as she raises it to her mouth, she awakes.
She knows what she has to do now, though, and the others awake to find Maugra praying through dry, chapped lips.
Teun hears the prayer, and fills the waterskin repeatedly throughout the day, and through the two days that follow. Teun likewise shields the group from the worst of the elements during that time.
On the third day, sunburned, and heartily sick of the rations Garnet has shared, the group reaches the far door. It opens to a depressingly mundane hallway, which extends 20 feet before them, before dead-ending, with doors on the left and right tunnel.
Looking back into the desert they've just left, the group sees an ordinary room, albeit one that's a little dusty and sandy.
