A few trama roots stick out of the dug out walls lower in the Bitter Wind's basement, seems like they should be tree roots. No khalaan connection that I know of
TR is suffering from a glut of pocket realms -- OE in itself has three, and two of them are in the Mages Guild. This is way to much and only serves to cheapen future pocket realms planned, e.g., for Master Dral. It was proposed on Discord that one of the OE MG pocket realms, "Hide and Seek," which is Rakanishu's old quest showcase, be moved to another project, namely the Mages Guild in S:HOTN's Markarth Side.
Rakanishu was happy with the idea, so we should do it.
The book "T_Bk_DefenseOfMorrowindTR" is repeatedly used in incorrect places. The book contains information presented as strategic by the author, that should by no means fall into the hands of enemies of the Empire: it seems to me it should only be found in Imperial-aligned places, and even then probably not in public areas.
Exemple: about Fort Firemoth, "This could be a massive weakness should an invader know of it". Dude, your book is for sale in three major cities.
The Omaynis is lacking a topic. You can only ask about it in Andothren, but in the city itself, no one will talk about it, even the governor. And it's not that small.
Another thing is the local area/economy thing. Some places have it, some don't, it feels kind of random: for example Menaan has it, but OE doesn't. Maybe get rid of it or leave it only for important settlements?
