There is a wood elf hunter named Ellegrin in the Malacath shrine of Hummurushtapi, in the Armun Ashlands, who is nonhostile despite the other inhabitants being so.
There is an item in a cave in the Armun Ashlands (lost the name, sorry), called the Water Spear, that has the effect of Water Breathing for 100 points - Casts when Strikes. This feels strange as you would have to hit a creature in order to utilize the out of combat utility of this item.
Also, that same cave was filled with skeleton enemies, various hanging skeletons, and scattered bones, including a necromancy-style book or two, but no necromancer or explination was found.
If the player acts fast, Aldaronwe can be killed before her dialog opens. The other highwaymen do not react and can be killed, but the quest will not close.
There's a non-journal encounter with a Nord, Harryk the Rude, standing on the road west of Teyn. He offers you to buy a barrel of pickled fish for 50 drakes. If you do, he puts the barrel into your inventory implemented as a potion with 4 effects (one of them is drain personality 20) that last 900 seconds.
Hello. I was playing a bit, and found this particule emitter somewhere visible by the player. I have no mods that edit Tamriel Rebuilt's terrain, and no mod seems to edit this entity/object/whatever it is called too (based on the ori command).
