What's the trigger again? I want to complete some guildquests before tackling the elven lands, but I'm to progress too far and getting banned in the mainstory line.
Getting a moonstone is one trigger. The other is the trial of the ancients. They do sell health potions in the elven outpost if the sell buyback doesn't work.
Remember to talk to emendore after the argalia. Quite often I go back to fargrove to confront okatta and Fargrove is still closed because I have not spoken with Emmindore the second time.
