Nightmare Sans (passive)

They have no home and live under the Tree of Emotions in any conditions. Dream is a very cheerful person and often tries to talk to his brother and support him if needed. The brothers have no friends or relatives besides Nim (the Tree of Emotions), as there is absolutely no civilization in this AU.

Nightmare is Dream's older brother. Their mother is the Tree of Emotions, and they are the guardians of the apples it bears. There are two types of apples: negative and positive. Nightmare protects the negative ones, while Dream protects the positive ones. They have a fairly good brotherly relationship. Nightmare is quite self-satisfied and arrogant, a brother who thirsts for more and more knowledge, even if it's dangerous. Therefore, he often reads under the Tree of Emotions. He's not very talkative and is overly serious.
