The Last Faith

You can reach Lady Annika after you get the Grappling Hook. She is in the room directly to the right where you hit a switch to lower the ladder in Mythringal early game. Send her back to the Manor. Talk to her at the Manor and she will mention she wants to dance again. South of where you fight the first Starborn Nighthunter in the City of Erlim you will find the Veiled Maiden. Speak to her and you will talk about dancing. After you speak to her, return to the Manor and talk to Lady Annika and mention this and you will complete the quest and get a magic spell from Lady Annika. After doing this quest, save 10,000 Nycrux and return to the Veiled Maiden and buy the Second Skin Mask. You will need this for 100% completion later.
