Sova

Sova was a Kenku inhabitant of Balvan's proto-nation within Mount Pillar, who was responsible for warning Balvan of the attack of the Giant Guisarme and his Westriders, pursuing Thungrim. Sova later watched for Pelor in "the other plane" after his (unknown to the Pillarites) death at the claws of Tiamat, while Balvan watched from the Shadowfel.
It is unknown exactly what happened to Sova after these events, but is by the time of Swayne and Balvan's first meeting described as being "wise and long departed", having left the granddaughter Znannya.
