Hammerlorne Level 3 - stuck (SPOILER)

[Gorgon Rider]

Okay, so I grabbed the Crux of Fire and headed out. Ran into the group of angry dwarfs right after the portal back, and made short work of them, but the portcullis is down. Is there any way past that if I didn't pick up a keg of powder or am I in a 'necessary reload' situation so I can go back and get a keg (and is a keg of powder going to work to get that open)?

I did a search but did not find an answer to this.

There is a lever northeast of the portcullis on your side that will help you get out. Grab a torch and search along the rocks to your north.

Thanks. Found it. I don't know how many times I went by it and never saw it. I'm blaming late night and the lighting of the Gravedigger's Light spell.

Those darn dwarfs must had a secret entrance anyway. i closed the gate before fetching the crux and there they where standing anyway. i guess they had help from BW but i showed 'em and fireballed 'em good :)
