Shun was as normal as any pony unicorn could be though he had always a knack for potions and powders. He had a bright future though on the night before he was to take begin his life work he had been up late working on a few formulas. This did not bode well for him as he had one too many and lost track. A big explosion erupted and his entire home was gone. Many in Trottingham had seen this as a bad omen and decided he was cursed. How else could such a bright unicorn cause such a bad accident. Many insisted he leave and it wasn't till he was out of the hospital that a mob came to drive him out.
Not being able to blame them he left. Running out into the night and not caring where he was going. He left his old life behind and took on the name Shun Obsolete. As he was shunned and his knowledge of alchemy was seen as obsolete and useless by all in Trottingham. He stayed away from anypony that he saw and one day found his way to the Everfree forest. it was here amidst the monsters... plants...trees...and animals that he found a home for himself. It was by pure luck that he came across the ruins of the two princess sisters. He found much of what he needed and made a home for himself deep in the hidden dungeon of the ruin remains.
