The Gospel (ゴスペル), also known as The Black Orbment, is a powerful and mysterious artifact in Trails in the Sky FC and SC that had the ability to shut down nearby orbments. This ability was called as the Orbal Shutdown Phenomenon. While the exterior looks ancient, the orbment appears artificially replicated with modern materials with no seams or maintenance panel to access the interior. There is no caliber inscribed on its surface.
In Trails in the Sky SC, the Gospel is revealed to be part of a plot formed by Ouroboros member and Anguis Georg Weissmann. This plot was known as the Gospel Plan, in which he planned to bring back the Liber Ark which contained the Aureole, the Sept-Terrion of space, which he wanted to obtain for his own use.
