Sheridan is summoned to the Interstellar Alliance's headquarters on Minbar after an enigmatic message suggests a looming crisis that could unravel the delicate peace he once fought to achieve. Accompanied by his wife, Delenn, and his steadfast friend and former security chief Michael Garibaldi, Sheridan embarks on a journey fraught with danger and uncertainty. As they travel through well-established and obscure star systems, they encounter remnants of old enemies and the emergence of new threats that test their diplomacy and resolve.

Reaching Minbar, Sheridan and his companions discover a web of intrigue that threatens not only the stability of the Interstellar Alliance but the fabric of reality itself. At the heart of the conspiracy is a power that can manipulate time and space, challenging the very principles of the alliance. Struggling to address this insidious menace without sparking an interstellar war, Sheridan must navigate a complex landscape of old allegiances and new alliances.
