GodlyTem

Saracas is one of the Temmies that inhabitant Waterfall. They are a loyal, trustworthy type, and fight you on a Genocide Route.

Story
Saracas was born during the Human-Monster War. They were among the Fighters that tried to fight off the humans, but was unsuccessful. After leaving the RUINS, they were the first Temmie to live somewhere else than the Temmie Village, the village of all Temmies. They originally lived in Waterfall by Napstablook, but moved to Hotland around the time the first human fell. They worked for W.D. Gaster, and witnessed Gaster`s death, and was the only Subject besides Sans to survive, the rest going Grayscale and holding pieces of Gaster.

Gameplay
They can be found in Hotland after Muffet`s battle, and will talk to you about how everything just goes by too fast. If you are on a Genocide run, they will be one of the only NPCs around, and will talk to you about how on another timeline, the world might fall apart. This is hinting that Saracas may have knowledge of the timelines like Sans.
