Description
Two brothers had ran up onto a strange mountain. As they were messing around, the younger one accidentally caused a rock slide, sending them down a dark pit, the impact killing them instantly.
After Dark Sans fell into the Undergrounds with his brother, Pyrrhon, the two mythical creatures decide to stay in the Undergrounds. After their death, they refused to die and the two made their bones come to life. Dark Sans is the older of the two and loves to make the younger one cringe with his bad puns. Pyrrhon dreams of joining the Royal Guard and believes that's capturing a human will do just the thing.
After meeting Pit, Dark Sans adopts the little one like another little brother, enjoying his dorky and shy personality.
