Fallout Equestria - What Once Was, is a side story written by Brony With A Fedora.
The story follows Bluestone and Stormy Skies (siblings) after they awaken from a cryogenic sleep. As they travel the wasteland they gather friends. The cryogenic storage was an experiment, to be clear, and no other ponies were signed up.
Bluestone - A male unicorn with an extensive knowledge about facts that were useless, but quickly gained value in the wastelands. He is also one of the siblings who was in cryostasis.
Stormy Skies - A female pegasi with above average skills at flying and a deeply emotional personality. She was also one of the siblings in cryostasis.
'Blue' Synthesis - A female synthetic pony modeled after an earth pony, she is most likely the only sane member of the party. She also, due to her being synthetic, has an affinity for computers.
'Delta'- A male unicorn who has an affinity for any sort of transmutative magic. He is also easily swayed. He never tells his real name, but Delta isn't his birthname. He is also boastful and can pick locks.
Rose - A female unicorn with a menacing appearance. She is a very kind pony, and her magic consists mostly of healing spells.
Sandy Shores - A female earth pony who mainly strives to be special. She has a great amount of skill when confronted with mechanical problems and can repair almost anything.
Yang - A unicorn colt who has a liking of magic and confronts most problems head-on. He was abandoned with his twin Yin.
Yin - A pegasus filly, she likes anything related to flying but is shyer than most ponies. She was abandoned alongside her twin Yang.
Refrences and Extra:
Most of the weapons I've used are confirmed in either the 'canon' weapons list , or the side stories weapons list, however i do have a few unique weapons.
The two twins cutie marks when combined form a complete yin yang.
