the blood running through your veins

[Halsin Silverbough]

Something doesn't feel right, but you have yet to figure out what it is. It doesn't take too much time, though, as soon as you speak your thoughts out loud - that the tieflings are supposed to stay, that you have given them shelter, that they can stay for as long as they need to.
They have been a lot more things happening in the grove than you anticipated. A lot more things that seem to have gone astray while you were gone, and Kagha wanting the tieflings out - you do not know how to feel about it.

You have named Kagha First Druid in your place, while being away from the grove. You have entrusted her with not only the druids but with the tieflings too, and now hearing that she has gone astray with shadow druids being mentioned -

What happened to the tieflings?

Because she hasn't told you yet about them; hasn't told you if they are well and alive. Kagha is on your list of people to talk to, since Nouzin makes it seem like she is still alive as well, speaking of her as if she is at least.
