I'm not sure I'm following.

You said:

1. You told Minthara where the grove was, and

2. You didn't go to the grove to protect it from Minthara's raid, but

3. You did kill all three of the goblin leaders.

How did you kill all three of the leaders if you didn't protect the grove from Minthara? Are you saying that Minthara's raid slaughtered everyone in the grove, and then you killed her afterwards?

If that's the case, of course Halsin is upset. You told them where the grove was. You let them murder everyone in the grove.

Or am I misunderstanding something you're saying?
