Well, considering the specific traits of the Hero character, I don't see any problems with Sarnissa returning to the game as a result of such a rescue (as I mentioned in the chat earlier, the possibility of recovery exists, just not under these conditions). On the contrary, I would be curious to see what impact this event would have and how her story would develop further. But there are a few points I would like to warn you about:
1) Continuing the game in this case will start with a journey to Melkoria or the intention to do so, and since I lead everyone together, all characters must have some reason for this.
2) By this point, you should understand that the "difficulty" of certain things in my games is determined not by how strong the characters are or how much time has passed since the beginning of the game, but by the location, enemies, and events. And Melkoria holds many dangers.
3) You can find out that Telani went to Melkoria with the help of the Eye, but you won't be able to determine the exact location of his house, given the nature of the area. For this reason, you will have to wander through the depths of the forest in search of this very house.
