Use them to invoke the spirit of Omenkiller Rollo.

Rollo's spirit, renowned as the original Omenkiller.

Once a celebrated perfumer, Rollo imbibed a concoction to rid himself of emotions, thus empowering him to carry out his dreadful mission, the pursuit of the Omen.

The ashes can be discovered within the confines of the Volcano Mansion.

After a conversation with Tanis, agree to join the Volcanic Mansion, obtain the key, and open the first door on the right.
