Not much is known about Syx's life prior to the fateful night in Ādīsi Geneti where she met Shayla Fitzreine, Ashraiah "Ash" el Sabine and Qau-dibab-āy'ḥāk-āy'āda. What is known is that she was in excess of three-hundred years old and was born in The Grand City of Mor'Koc. She was a member of the Mor’Koc Militia during The Siege of Mor'Koc where she earned the rank of Captain. She also had at least one son at some point, and spent a deal of time working as a maid at the Grand Order Training Tower, which ended when she stole a spellbook and fled. She then spent some time learning the spells in it , becoming particularly interested in Necromancy, before ending up at some point in Mouldtown.
Preferring to remain disguised as a pink-haired Wood Elf, Syx travelled to T'Kashire as a founding member of The Band of Misfits, and with them and later Kadar Rachid began to assist with the rebuilding of the village, helping to empty the mine of an influx of undead, being part of the team who defeated Bartimeus Quinnlee in the abandoned temple, and taking part in Duke Erwen's Tournament, where she came third in Archery and second in Jousting, despite being increasingly intoxicated throughout the event. She found herself often acted as the straightman to the other three following Kadar's introduction to the team. However, this was only when she was sober - Syx was noted to be quite a heavy drinker with whiskey on the rocks being a personal favourite, but ironically several of her greatest feats were achieved while drunk.
Syx died on the way back from Balla, when a Drake crossed their path. She was hit by its tail and flung into a tree, dying immediately from blunt force trauma which broke her neck and crushed her ribcage. Her body is interred in a small stone mausoleum in T'Kashire churchyard, which Ash and Shayla, both of whom became good friends with her over their time adventuring together, frequently leave flowers on. She is survived by numerous children, one of whom has become the companion of Willow Goldleaf, heiress to the Byrne family.
