I can see a Spirit Gate into it but it's not active, neither are 2 others - 1 east of Yurikago, the other west of Hankou.
I thought if I defeated Ariana (Primary Quest) it would open up but it doesn't. Defeating Ariana ends this campaign.
I've completed all the other quests.
If I knew how to upload the map I would.

Can any1 help please.
