The dialogue of the NPCs located in the Ashamul cave (southeast of Tel Ouada) is very weird and inconsistent with the rest of the game. The main issues I saw were uses of modern English and some broken English, and just overall the writing is a bit weird.

Thalin Thimalvel (tr_m1_thalin_thimalvel)

Another issue I saw with Athyn Favelnim (tr_m1_athyn_favelnim), who is apparently the brother of Seler Favelnim (an NPC you encounter at Raven Rock in Solstheim, you prevent him dying in a bar brawl). I thought it was cool that I found the brother of that guy purely by chance, and he mentioned the fact that I prevented the brawl and saved his life. However, if you choose the 'Solstheim' option right after, he acts as though his brother was killed:
