The one true Oavailius. Also because she has the most progress. ---
[Lore relevant to outside off Ff14 and refers to the actual character she is based off of. Doesn't make sense to you, but it does to me!]
Oavailius is formerly an eldritch deity who is now in a weakened state due to her absorbing an intense surge of black magic cast by unknown sources to protect her empire. Her eldritch form regressed and took upon the common form of a humanoid to remain stable.
Her magic affinity is greatly weakened, and the empire scrambled to accomodate for their fallen goddess. Rituals, cleansing baths, research, and rest were all prescribed in hopes their deity can recover. In the midst of it, attendees were casted in under the name of Starflight Fleet. 4 talented warriors all with the sole duty to protect their mistress.
Seuuam-siia is a Black Unicorn Fauna, hailing from a far off capital. Her immense devotion to Oavailius stems from Oavailius's having driven away soldiers of the capital who had declared Seuuam-siia a criminal for abandoning the court of Arcanist; something she learned was because all Unicorn Faunas were to never leave the capital or else it be treason to the king. As a Black Unicorn, she had been treated harshly and unfairly both by the court and her own family and seeing an example of what she herself deemed hideous (Oavailius in Eldritch Form) being treated in kindness and glory made her cling to Oavailius's Empire. She had hopes of finding her own place within a kind empire. She weilds a broad greatsword that is actually just giant scissors.
Phatthana is a human prodigy in the Marauder Academy and was actually just an accidental attendee. She got pressured to audition to the calls and didn't expect to find herself getting a spot. Still, she found the mysterious deity to be interesting and only stuck around in hopes to learn more with an obsessive near manical interest in experimenting with the mysterious magic of eldritchs.
Sangtua is a Raccoon Fauna who grew up on the streets. He's been in an out of jail several times for many related crimes before leaving in his teen years. However, due to lagging administration paperworks, he'd been wrongfully thrown back into the cells far too many times. He hardly cares for the deity, and only took the chance to audition as a way to get out of the loop of unjust jail time.
Vaangyi is far too soft spoken to be a warrior, yet his determined stance in wanting to protect the deity comes from how he obsessively clings to any kindness shown to him. Given that Oavailius was the one to offer him another chance at life after he faced the execution block for being wrongfully blamed of his brother's murder, he took to being overly protective and obsessed that it bordered turning into a badly covered up crush.
Oavailius is a stand alone artist persona. Her lore can seamlessly connect to the TWST verse and is shipped with Leona. Vaangyi is the love interest in non TWST settings.
