Eris was born into a poor family, in a time where elves were rare and sought after for many reasons. But her parents weren't in a position to care for a child and so Eris was sold to a brothel at a young age. Elven girls were especially high value in the slave trade for their eternal beauty and healing abilities for the more cruel clients.
Eris spent her childhood and most of her teen years in that brothel, but when her powers finally manifested she hadn't expected lightening to crackle at her fingertips. In a fit of rage and panic she had ended up burning that awful place to the ground with her lightening and was imprisoned because of it.
She didn't know how long she spent in that prison. It was below ground. A massive mine shaft for mining a rare ore, one that was crafted specifically for nullifying elven magic. They'd treated her worse than the brothel did. She was starved, whipped, beaten, and when the guards got drunk, they had a lot of fun with her.
She hadn't escaped, not really. After a particularly rough night at the hands of those guards, they took it too far. She was assumed to be dead, and they took her to a steep hill at the back of the prison. It was a steep incline, at the bottom was a raging river and that's where they'd tossed her body, thinking she'd be carried away by the current and never seen again. But some force had heard her suffering, the pained whimpers as she rolled down that hill, hitting rocks and roots and branches before landing in a shallow part of the water, her limp body catching on a fallen tree
She couldn't tell if she was awake or asleep, but a being appeared out of the dark nothingness. Male and cloaked in a black robe, his face obscured but the energy that surrounded him was awful. Dark and ancient. He promised her she'd never suffer again. He would gift her dark power. A power the ancients used a long while ago. The ability to phase in and out of shadow and to call upon unnatural forces, dark creatures that didn't belong in any world and in exchange? When she died, he'd claim her soul, and she'd be locked away in whatever horrid place he came from, and she accepted without any sort of thought except revenge.
She had eventually gotten revenge on those guards. That prison. No one knew where the creatures came from, or what they looked like. Large beings of shadow that moved too fast to detect much. Leathery skin, rotten maws filled with too large teeth, obsidian black eyes. She was a God. Comanding her lightening and the things of the ancients
After her revenge she had wanted to settle down, put all her anger and pain behind her and heal in peace. It had taken a while, but she had saved up enough money to buy a run down little building which she had turned into a store.
Eldritch Elixirs sat just at the edge of the city. Eris had restored the building. It was painted a deep blue, golden runes were painted along the entire doorway and on the window panes. Creeping ivy covered one side of the shop, crawling over a section of the peaked roof like a disfigured hand. The shop was cozy. Eris sold elixirs, alchemy ingredients, and other oddities and curiosities. It was a peaceful life. The one she'd always wanted. Most days she found herself sitting behind the counter writing in her business ledger or entertaining a small creature she had summoned and kept as her little pet, finding the dark creature too cute to send back to the void. It hung out on her shoulder most days, and she'd have conversations with it, able to understand the two toned growls in a language that was not of this earth.
