Ghost of Adventurer:
You don't have 1000 relics yet? Hunt the monsters in the Imperial Tomb, you should be able to obtain them. Keep trying! Collect 1000 relics and bring them to me, I'll give you a very nice piece of paper, supposedly a recipe for some sort of weapon.
Ah, I see that you have the sepulcher pass! Ask the nameless ghost near the Four Sepulchers, he'll tell you what it's for.
"I'll continue collecting relics."
"I want to stop collecting relics."
