i have been flying trough the map w the gunwitch and dryad, eventualy i was able to parkour my way up on the yellow tower northeast from your vieuw of where you spawn on the ship with the cores, it depicts a crystal with wings and an evil set of eyes, i also flew to the highest point of the map using the yellow tower giving a good vieuw on the map itself (the large tower that has 2 spawns in it that also has one of the skeletons for the secret pirate thingy hanging on one of the wooden beams)
