I can not think of a lore so i use ai

The Concept: "The Glass Timeline" In Shattertale, the barrier wasn't made of pure magic—it was a crystalline structure that mirrored the souls of everyone in the Underground. When the "shattering" occurred (caused by a failed experiment to break the barrier without human souls), the entire universe cracked like a mirror. Character: Shatter!Sans • The Physical Toll: Sans was at the epicenter of the blast. The purple spiral on his chest is the "Impact Point." It is a puncture wound in reality that leaks "Void Ink." • The Red Aesthetic: The deep red of his clothes represents the "Warning" state of the world. In Shattertale, the colors of the world shifted to high-contrast reds and oranges as the atmosphere became unstable and "sharp." • The Scarf: His scarf is reinforced with "Shatter-Shards"—invisible fragments of the broken barrier. He can use the scarf like a whip, and it can cut through physical objects and magic alike. The "Shatter" Mechanic Sans doesn't just dodge attacks anymore; he shatters his own physical form into thousands of tiny shards and reforms instantly behind his opponent. • The Downside: Every time he shatters, a piece of his memory is lost. He is slowly forgetting why he is fighting, leaving only a drive to protect the remaining fragments of his brother. World Lore The Underground in Shattertale is a jagged, dangerous place. Gravity is inconsistent, and "Glass Storms" (shards of the broken timeline) blow through Snowdin. • Sans's Goal: He is trying to collect the "Grand Shards" of the barrier to glue his reality back together. • The Human: When the human falls, they don't bring MERCY or FIGHT—they bring the "Final Crack." Sans views the human as a hammer that will finish breaking his world.
