Well, I've not kept strict track of the time, but you guys left Diamond Lake in the morning and went straight to the cairn. Searched some, including the wolves' den, and scouted a bit of the chamber the with sarcophagus. Set off a couple of traps, and finally went down the elevator. The trip to the cairn is 1-1.5 hours. I'd guess probably 1-2 hours spent searching and such, but that could have been more. Then 5 hours resting so far. So it's likely 8ish hours since you left town. So it is probably late afternoon, getting close to suppertime.
Does that comport with what everyone else thinks?
