So, I'm starting to feel like I made the trip to Skuldafn woefully unprepared. I've managed to take down a fair number of the mobs that awaited me here, but I'm out of health pots and pushing the limits of my carry cap. Is there any way I can go home to sell my loot and re-stock, without having to re-load the game?

I've tried re-calling the guy that got me here, but he's not coming. Fast Travel seems to be disabled. I'm on the PS3, so console commands won't help.
