Feverish Attempts is a limited Memoria released May 29, 2025. Xavier and Jeremiah track Isaiah to a psychiatric hospital on the outskirts of Linkon City. Isaiah has deteriorated severely — his Philos-born physiology has aged him far beyond Xavier despite their comparable age, a consequence of extended metaflux exposure. He is violent, incoherent, and unreachable — except for one brief moment of recognition when he sees Xavier. Xavier and Jeremiah sedate him and remove him from the facility to an undisclosed safe location. The Memoria establishes that EVER has been monitoring Isaiah and that controlling him is a step toward controlling Xavier ('if they can control Isaiah, then controlling Xavier shouldn't be far off'). This is side content, not main-narrative canon, but references established main-story lore elements including the Backtracker network and EVER's long-game against the Lumiere faction.
