Ernak was the nephew of the skandian sea-captain Arndak and was serving aboard his uncle's ship Spraydancer.
He was twelve years old.
When Spraydancer was set upon by Zavac and his pirates, Ernak was held hostage by one of the pirates to force Arndak and his crew to surrender.
Later, Arndak and Ernak were locked in the hold of Spraydancer and the ship was sunk, killing them both.
