Melina

Melina is a mysterious, young woman in who offers an alliance with the Tarnished to help them on their journey.

At one point she'll visit the Tarnished at a Site of Grace and offer assistance in return for the Tarnished to bring her to the foot of the Erdtree. Once accepted, she'll then give the Spectral Steed Whistle which can be used to summon Torrent.
