Well, if you're at 7 and don't have the Jeweler, then you probably get it at level 8. I neglected to make a note of the precise level when I was there, I'm afraid. You get access to the Cold region at level 9 - I know that one for sure. =)

Sadly, you're simply going to have to manage with that castle until you can level up a few times. Yeah, I know that's annoying.
