So i was wondering around Enderal's desert, and I found a cave with a cool looking entrance name "Old Ishmartep"
I went inside and killed a few bugs, then i find myself facing this huge steel door made out of bars, but i cant find a lever to open it.
Is it a quest related thing, where you can only open it when you have the related quest, or a bug?
I am temped to use TCL to get passed it, but i dont want to risk breaking my game, so i just saved there and quit playing for today until i can find out what its about.
Please give me an answer soon, thanks.

Oh man, thanks for the quick reply man, you're awesome!

And there are no quests, just loot and a lot monsters with really good XP for levels around 20-30.
I once went through that with my level 28 stealth character without killing any monsters except the boss. It was fun sneaking around distracting them with a bow.

The boss at the end ishmartep has a golden statue that is part of the lost hearts quest so make sure you take it.

Yeah i found the statue, but i already did the wishing well quest, since i found the statue in a random loot chest a while before .
