Military action
The Cloakmaster, Teldin Moore, gains the Spelljammer and becomes her captain. Squadrons of neogi, illithid, gnomish, scro, elven, dwarven, beholder, and multiple human groups converge on the legendary Broken Sphere to either take the Spelljammer from Teldin's control, or help him protect the Spelljammer from the other groups. Hundreds of vessels were involved in the battle, and over two-thirds were destroyed. The Spelljammer itself was the subject of conflicting reports, with some saying it was destroyed, others claiming it fled into the Broken Sphere or otherwise escaped the battle. In any event, the Broken Sphere began to mysteriously close following the battle, and none have been able to enter it since.
