A limited-time event arc introduced in July–August 2025. Xavier explores a location called Sindersfell, which is framed not as a step toward success but as a mistake made during his journey back to Philos. The 'Sacred Path' sub-event has him investigating Sindersfell's legends connected to the route home. His Ardent Oath in the King of Darknight companion identity later summons 'mirages of Sindersfell,' cementing it as a meaningful location in his arc toward potential coronation on Philos.
