Gloomoor Side Quests

The Eye of Hell:

This quest starts with a mage who is standing by a portal South of town:

He will attack you the moment you click OK  his 2 Sakkara Priests and a Gargoyle that he summons will also attack:

 When Ilim dies he will drop a portal rune:

Now enter the portal, which will bring you to a cave:

There you will have to kill a horde of Fire Demons and a few Wyverns:

When they are ALL dead walk on this stone slab at the end of the cave to exit it:

You will appear back at the portal South of Gloomoor which is now closed:

Unlike most quests there is no NPC to return to for a reward, the moment you get back from the cave a Mission Completed message pops up, so you are now finished.
