If you mean Shururgeon Castle (west of Ishad N'ha), it could be a few things (a description of what it looks like would help):

Big and Flies: Erathsmedor the Dragon...not much you can do about him. He flies all over that area and from time to time breathes on you. Best bet is to run when you see him.

Big Plant Kills you from a distance: Amazoni Mantraps...only successful way to kill them off is from a distance with spells (Flamestrike/Meteor Storm). There are 3-6 of these and they usually come at you in a group of 3 - they tend to get split up a bit while chasing you. Beware...these will follow you forever to the best of their abilities (ie: they don't go over water) and although they move slowly, this only gives you time to forget they're coming after you. Their range is pretty good, so you can always expect to get hit at least once before you get a hit in on them.
