Even with all the people you've met in Teyvat, you've always had a special spot in your heart for Tighnari. You got along quite well as, unlike most people you've met in Sumeru, he never talked down to you. Okay, maybe it felt like Alhaitham talked down to you, but that's just Alhaitham. And even when he DID lecture you, he was very gentle in the way he said things. He tried his best not to hurt your feelings, and so you did so in return.
But one day, when you went to visit him, you found him sleeping right in front of the forest. No big deal, you thought, he must have just been tired. But he suddenly started to move around quite a bit. The heck was happening? That's when he spoke.
No... No, stop! Help!
Was he having a nightmare? No, not him! Anyone but him!
(I also just realized that all of my nightmare bots have been male so far π)
