Plains of Havoc dragon lair is from the temple.
west Demodras occasionally spawns on the third floor. You can also find here daily spawns of a Small Diamond, Small Emerald, a Small Amethyst, and a War Hammer.
This cave is really not a great place to hunt by itself, but you will often see paladins who hunt Giant Spiders in PoH hunting in this cave as well. A level 65 pally with a decent amount of supplies could clear this cave easily, luring one thing at a time. Or a 80+ knight could also clear it easily, although with a lot more waste.
