A few questions: how do I advance the Temple questline after the fox invited us to the massage? What gift should I give to Linda? Annnnnd... are there more content for Mistyra after rescuing Linda?
Talk to the NPCs blocking the way, and get them the items they're looking for!
I don't think Linda has too many things you can give her yet. Her route is still in progress
Not yet, but definitely planning to get back to Mistyra at some point!
Gave the cat and the fox their respective stuff, what's next?
Continue upstairs and give more.
Until you get a Clear path past them.
It will take a few items at least.
