 * Brazier of Beckoning (Jarien and Sothos) (Provided)

Description
The siblings, Jarien and Sothos, decided to join the Scarlet Crusade upon the disbanding of our mercenary company. They took the right piece of Lord Valthalak's Amulet with them. Good riddance, I say, but we need that piece back.

From what we could gather, they were actually slain by Grand Crusader Dathrohan himself for failing the initiation rites inside his chamber in the Scarlet Bastion.

In any case, we... meaning you, are still going to need to retrieve that piece of the amulet.

Rewards
Upon completion of this quest you will gain:
 * 11900 XP (or a compensation at level 80)

Progress
Does this mean then,, that you've already put the souls of those two fools to rest and recombined the pieces of Lord Valthalak's Amulet?

Completion
I suppose it's for the best that the souls of those two have finally been put to rest, even if I didn't like them while they were alive. In any case, we have what we were after, and now the amulet is reassembled! But we still have the hardest test ahead of us.

In order for the brazier to be attuned to calling forth Lord Valthalak, there are a few more items that need to be gathered and brought back to me here.
