The general consensus about the existance of the Dwemer in TR is that they are extinct and will stay extinct. TR will not welcome "survivor" dwemer in the projects mods so please do not create quests/NPC's or any other lore to conflict with this in your mods.
The lore clearly states that the Dwemer are extinct with the exception of Yagrum and this will not change.
Only under the extreme circumstance that Bethesda changes the lore on the Dwemer will TR review this policy.
