Went to Aerlinthe again. Figured, "I'll just try the jump again -- if I make it, I'll log, and wait for everyone to find a good time to run the quest, since I've gotten everything we need -- I just have to make the jump."
Went to the ledge. Saw the grate. A jump to the wall, with a slide down to the grate didn't work the first time. Thought I'd do a shift/jump this time.
Missed. Not sure what happened, but it didn't stick.
Why the fuck do I even bother?
