Ashen remains in which spirits yet dwell.

Use to summon the spirit of Oleg, the Banished Knight.

Oleg, known as one of the two knights called the Wings of the Storm, was cast out but later caught the attention of the Grace-Given Lord. He earned the honor of Erdtree Burial after slaying a hundred traitors as the Lord's hand.

The ashes are located in the Heroes Cemetery of the Nimgfu Frontier, and you must enter it from the Drifting Cave at the birth point. To access the cemetery, you need two stone sword keys to break the seal.

You can obtain the ashes after defeating the Boss Rotting Dryad in the deepest part of the cemetery.
