The dungeon overlord's name

Before entering the dungeon, you must correctly name its overlord. The statue at the entrance gives directions: "Seek the four warriors, north before south, east before west, subtract the castle's name, and you'll pass the test."

The four warriors are the statues in the corners of the castle. Visit them in the order given: Northeast, Northwest, Southeast, Southwest. Write down their names one after another: JODELLE LEADBEST ASTRIEL TESHY. Now "subtract the castle's name" — remove any letters found in WHITESHIELD. What's left is the answer: JOABARY.
