Special moves:

Phoenix
Phoenix flame-Sardonyx alights and fills the entire arena with flames, scorching her opponent.

Rainbow chain-Sardonyx flies around her opponent repeatedly, a flaming rainbow extending from her tail. When she stops her flight, Sardonyx's opponent has been tied up by her rainbow trail.

Phoenix scream-Sardonyx lets out an ear-piercing scream which deafens her opponent, leaving them open to attack.

Human
Crystal phoenix-Sardonyx becomes encased in a crystaline structure and appears helpless to her opponent. While her opponent is moving towards the crystal phoenix, Sardonyx appears in a burst of flames behind them, and delivering a powerful uppercut.

Phoenix song-Sardonyx begins to sing hypnotically in her native tongue, which puts her opponent into a trance, allowing her to attack at her leisure.

Fire hair-Sardonyx's hair ignites, which looks quite impressive, and she whips it at her opponent, burning their face.

Weapon: Firebird staff (staff made entirely out of flames with a small firebird on each end)

Weapon move: (can only be done in human form)

Firebird's hold-The two firebirds on Sardonyx's staff ignite and fly at her opponent, stealing their weapon if they have drawn it, or scratching at their eyes if they don't have their weapon out.

Fatalities:

Phoenix
Supernova-Flames and bright light eminate from Sardonyx's body as she prepares to dispatch her opponent. The arena is then engulfed in flames and a bright light. When they fade, there is no trace whatsoever of Sardonyx's opponent.

Phoenix's pity-Sardonyx takes pity on her defeated foe and bows her head as she flies away.

Human
Crystal death-Sardonyx encases her opponent in a crystaline structure that seems to be aflame. Her opponent then dies of suffocation, and Sardonyx keeps the flaming crystaline statue as a trophy.

Phoenix's kiss-Sardonyx walks up to her opponent, her hair aflame, and kisses them. She then moves back as her opponent turns bright red, and spontaneously combusts.

Story: Sardonyx has been appointed one of the two official representatives of Geal'm'athair to Medeva. She stays in the Shuni Avin, but rarely makes her presence known anymore; Sardonyx is still recovering emotionally from Eclypse's apparent death. Although she is loyal to Rai, some of the fighters in the temple begin to wonder when Sardonyx disappears for days at a time.
