Capital or Greater Restoration Potion

Two of my party members are on Death’s Door. The tutorial says that I need healing from a healer in the Capital or use Greater Restoration potion.

Where is the “Capital”?

Where can I locate Greater Restoration potion?

I am currently stuck in the Old Sycamore caves.

The Capital will turn up later, for now rest at Oleg’s Trading Post, in the bed.

Brukov,

Are you saying that resting at the Trading Post will remove the “Death’s Door” issue?

Yes, that is what I’m saying. Anywhere that counts as a “safe place” will do it, Oleg’s is the first such you’ll find, then there’s a main one that will be pretty obvious once you deal with the Stag Lord. There are a couple of others, but they’re not so important.
