Phandelver and Below: The Shattered Obelisk

Boona instinctively puts a heavy hand on Bryonys shoulder as the old elf speaks....though she does not understand most of it....

"...Can you hear the shards? Can you hear their song?" Ontharyx smiles, and has a faraway look in his eyes. Nightblade's spell is beginning to lose its effects.

You only have a few moments of lucidity left before Ontharyx's mind falls back fully into the grip of the Far Realm's corruption. 

Nightblade:

Nodding to the transformed Drow and his sons, Nightblade suggests to the three, “Speak as family quickly as you will before your long journey home.  I pray you will find healing there.”  He then backs off to let them talk unless someone else interjects and wants to ask a question.
