Jude

Jude joined the system in 2015 and was the primary host until 2020. It formed as a fictive of Jude Mathis from Tales of Xillia but has a largely fluid identity and internal appearance, based on shifts in the fragmented alters that make it up.

Primary Identities
Jude is an extensive network of fragments which vary in intensity. Currently its most common manifestations are Jude Maxwell (Tales of Xillia), Crevan Espane aep Caomhan Macha, Iorweth, Jaskier, and Geralt of Rivia (The Witcher), and Shokrakar Adaar (Dragon Age).

Jude Maxwell
Jude's canon was largely compliant with the source material through Tales of Xillia. There was an approximately 5 year gap between the events of Xillia and Xillia 2, during which time he became romantically involved with Alvin. The events of Xillia 2 were also largely in line with canon, with the primary difference being Milla's long-term return from the Spirit Realm following the sacrifice of Ludger.

After the events in game, Jude formally renounced his family name before marrying Milla and taking on hers. He continued to research spirits and spyrites for most of his life with the support of his partners.

Crevan Espane aep Caomhan Macha/Avallac'h
Avallac'h's canon was largely complaint through the events of The Witcher novel series and CDPR's Witcher series. At some point in his travels with Ciri the two arrived in Thedas, although the events of their time in that world had little to no bearing on subsequent events.

Avallac'h and Ciri became romantically involved shortly before she sealed away the White Frost and married shortly after. They had two children, Duny and Lara, and eventually settled in Toussaint near Geralt and Yennefer's vineyard.

His canon's Ciri is also part of the system.

Iorweth
I will write this better eventually but Iorweth's identity is 25% being a trans man, 25% resenting humans, and 50% loving Vernon Roche.

Jaskier
Jaskier's identity is divided into two separate timelines: one following the events of The Hexer and one CDPR's The Witcher.

Geralt of Rivia
Most of Jude's memories as Geralt are directly from the Blood and Wine expansion for The Witcher 3. He was in a relationship with Regis and Dettlaff, who are also currently present in this system. Geralt's death occurred while trying to stop Dettlaff from attacking Beauclair.
