Jes-Tereth is the apparent Grand Admiral of the Alliance forces. She spends her time in Stormwind discussing plans most of the time, rather than going out to sea. She is apparently now Daelin Proudmoore's replacement. However, since the Alliance currently has no true hierarchy at the moment, rank doesn't mean much when there are no people assigned under them. While there are Alliance ships, it is unknown if she has ships under her or not.
