TR_m3_Ieran, TR_m3_Gevar, TR_m3_Guls should have unique responses in "velk" topic, as well as dialogue which unlocks it. The best way to do it is via greetings, imo.
Almas Thirr Silent Night misc quest has a conflicting dialogue in the final dialogue entry of Llandora, the questgiver. The one where she rewards you with various potions - she says that she's asked Narusya, the OE Alchemist, to send these potions to her to reward you. But since the whole task of the quest was for you to travel to OE and back and fetch a potion from Narusya, it makes little sense that Llandora gets a whole batch of potions from her immediately after you accomplish the task. It also cheapens the player's effort of bringing her the potion from Old Ebonheart.
According to the quest, the bedroom at the top of "Oran Plantation, Oran Manor: Main Tower" int cell belongs to Drolora Oran, the daughter of Atran Oran. However, currently, the room is filled with weapons and has Adamantium armor pieces, implying that Atran Oran is the real bedroom's inhabitant.
TR has fully duplicated the vanilla lines in the topic "soul sickness" which would otherwise not be available for TR NPCs because they have nolore exclusions. But in my opinion they *shouldn't* be available, because in our lore there is very little to none Sixth House influence on the vast majority of the Mainland, so this should not be a thing most people know or care about, and they certainly shouldn't have neighbours screaming in the night.
