Skye

Skye, the first human to fall into the underground after Chara, after King Asgore's decree to capture humans for their souls. Skye has the light blue soul of Patience and is equipped with her toy knife and a red, faded ribbon. The eldest child of her family, Skye grew up learning to look after their younger siblings. While their siblings were out playing one day, they wandered off into the woods of Mt Ebott, causing Skye to venture out to find them. Upon discovering her little sister's teddy bear at the mouth of a cave, Skye tucked it into their overalls and entered the dark maw of the mountain. She could make out two of her siblings fighting over a toy, way too close to the edge of a dark void in the ground. A crackling filled Skye's ear as she darted to her siblings, shoving them out of the way just as the ground cracked underneath their feet. The two siblings toppled to the side as Skye began her plummet to the depths below.

Skye is the protagonist of my Undertale prequel AU, Undertale Ruined. It follows Skye as they explore ancient and lost areas of the Ruins, encountering a variety of monsters that wish to either aid or hinder the first human in ages.
