The Ryton system contains the nebula where the USS Titan hides from the Shrike and discovers the nebula itself is a living, birthing creature.
The Ryton system holds a vast nebula into which Captain Liam Shaw orders the Titan in Disengage to escape Vadic's Shrike. Inside, the ship is pursued, badly damaged and pulled toward a gravity well while its power runs low.
In No Win Scenario, the crew uses an energy pulse from the nebula to recharge the Titan's systems and break free. The nebula turns out to be a living being, and as the ship leaves it gives birth to many jellyfish-like space creatures.
