Quick question - my character is a fighter, and I've completed the keep quest. So, I can go there, grab some cash, whatever.

I want to dump some stuff there that I've been hauling around for ages. But I read somewhere that with strongholds the map reference or something changes, and you can lose items you leave there.

Is this true? And if it is, when is it safe for me to leave my gear there?

It is safe to stash things there after the stronghold is yours. I once made the mistake of dumping stuff in a barrel before doing the keep and found it all gone after Nalia gave me the keys. Once she has given you her speech, though, you can stash whatever you like.

Cool - thanks. I feel better knowing that.
