I downloaded this mod and Im just wondering if anybody uses this then which npcs initate the three quests? and where are they?

I wanna try out the quests but hunting down every npc to find out which one will take forever lol.

Quests:

Forgotten Lore
The Conspiracy of the 7000 Steps
Relic's Revival

Off the top of my head, Relic can be found in Blackreach (I think it was the War Quarters).
