Odimasadra has weak loot for the monsters you fight. In total you fight 2 frost atronachs, 2 daedroth, and a storm atronach, all in a tight space with the final battle being both daedroth and a frost atronach all at once. In terms of loot, all you get besides a single exclusive potion is 2 very common books, a weak healing amulet, a single piece of gold, and a redware bowl. Compare to any other daedra filled location, like a ruin, and you usually get better stuff.
Dustmoth Legion Garrison kitchens have these two dried slaughterfish lying on a table with bloodstains and a butcher's knife. It looks strange to have blood beside dried fish.
The Tools of the Trade Thives Guild book belongs to Andothren and other Hlaalu settlements, not Firewatch, imho. It has thematic tool names that reference some Hlaalu territory places. And while it's possible that the book got shipped from the south by other TG members, it feels awkward to introduce it to the player so far away from the territory it was created for, in my subjective opinion.
DoD and Aanthirin are in need of more roads. In particular:
One, connect Uman and Bodrum here, and ideally, make this area a transition directly from SVM into RR instead of skipping through the AA for twenty paces. The cells are already in these regions, anyway.
