Sea Serpent

A Sea Serpent is mentioned in the background info as destroying an Elven fleet.
In the East a third, smaller force landed with the intention of forging passage from the coastal city of Tor'Quat through the Golden Mountains. But here, disaster struck the Elves. Even as their fleet approached the long bay reaches to the city, a giant sea serpent arose, striking down the lead ships and devouring the Admiral in charge together with the Elven illusionists, who were obfuscating the invasion's advance with swirling black fogs.Background
There is a pretty picture of a Sea Serpent right below Tor'Quat on the map. Coincidence??? (er, probably yesWe are now discounting any specific meanings to the marginalia on the map given Sparrowsight's comment of: "the decoration around the edges varies wildly from map to map. Some even had no decoration whatsoever, almost appearing unfinished.”Day 21-27 – The second week in Northlake)
Or could this possibly be a Kraken?
