- Sigrid Iceborn Defeated
An old foe of yours has returned: Sigrid Iceborn. Perhaps you remember besting her in a duel upon the Savage Ledge?
No matter, she certainly remembers you. She's insisting upon a chance to prove herself once more.
Personally, I think it's more a chance for revenge, but that too can be useful in this place.
I leave it up to you, <name>. Will you face Sigrid Iceborn once more?
