Mysterious voice

A Mysterious Voice appears during the Kindred Spirits quest in a cutscene talking to Sliske, who is standing in front of the Stone of Jas. The cutscene itself is viewed from this character's perspective, so his, her, or its true identity and appearance are completely unknown, apart from the fact that it is definitely (not) Xau-Tak, as confirmed by Mod Wilson. 

The words spoken by the mysterious voice appear in orange.
