Hey. I'm having trouble completing the quest with Grah-hoth. I can't enter skarragath. Micah tells me he's opened the gates but when i travel north from Erika's tower and encounter the 2 gates leading to Skarragath i simply can't enter the gates. I can step "into" the gate so my party vanishes but it won't let me move them into the area past the gate. I'm wondering what exactly i'm missing.
Cheers
