This AU isn't so much an alternate universe as a What If Marvel scenario, that What If being "What if Sora had a sister and Kairi wasn't sidelined?" With the happy plus side of me being able to headcanon and expand upon these epic games.
Main OCs
--------------------------------------------------------------------------------
Siara Senin: The protagonist of the Soul's Aura series, she's Sora's twin sister and shares a lot of features with her brother, despite their personality contrasts. She's a brunette with blue eyes, tanned skin, and is the shortest of the Destiny Islands kids at 5'4 when she stops growing. Siara went blind when she was about 7 in a swimming accident, which is when she awoke her ability to "see" people's auras and souls, allowing her to read their emotions as colors. When she doesn't actively use this ability, she has extremely limited vision, mostly just being able to make out lights and shadows. She is rarely without her red-lensed sunglasses, even at night, as they help to protect her eyes from brightness and further damage. She always has on her silver heart pendant necklace, which had been a present from her brother for their tenth birthday- which is when she had gifted him his crown necklace.
Siara is a more pessimistic and sarcastic than her brother, and a lot quicker to anger and frustration thanks to how people have infantalized her since the accident. Naturally though, she is a rather happy person, as seen by the yellow-gold color of her aura whenever she uses her magic. She mostly uses her nonchalance and sarcasm as armor so that people will be too frustrated by her to baby her.
Siara uses a Psikey, a golden, hollowed out handle that allows her to channel her aura through it to create various weapons or items. It's most commonly a walking stick when they're going through a new world until Cid manages to make her one, and in fights she switches between a whip, a single sided sword, and just sheer magic blasts most often. More options are avabile to her though, so long as she can project her aura into what she imagines (Kind of Green Latern rules).

Sakura Mizushima
The month older cousin of Riku Mizushima, Sakura shares the same silver hair as Riku and their mothers, although she has hot pink colored eyes instead of greenish-teal. She starts as the tallest of the main 5 Destiny Island kids, having a couple of inches on her cousin. She winds up the second tallest of them at 5'10, if you don't count her bun and wedged boots (6'1), which Riku (6'0) adamantly does not. While not present beyond the Destiny Islands prologue of the first fic, she becomes relevant during the Blind Destiny fic (timeline: companion arc to 358/2, but focusing instead on Kairi, Siara, and of course Sakura than Roxas, Xion, and Axel).
Sakura utilizes an enchanted Parasol in battle that works as a magic staff when closed, and a shield when opened and spinning. Her talents lie in defensive and healing magics, particularly Wind and Nature spells like Aero, Quake, Flower Shoot, etc...
Sakura is one of the most outwardly kind people in the Destiny quintet, though Sora has her beat on outright charisma as Sakura is a quieter presence.
