Olm's names are melodies, not easily transcribed, so we'll refer to this one as [A Beautiful Song]. She holds territory in the Sea of Sorrow, between Vralkast and the region of Khyber that leads to the Pinnacles Sublime, Ravener's Maw, and the Ossuary of Splinters.
She was encountered by the Maruk Ghaash'kala squad lead by Valaari, and requested a song from Bhaltair as a toll to pass through her territory.
