Reconciliation Debt

Reconciliation Debt is the total amount of damage done to the spacetime fabric by a ship going faster than light through Slipstream Space.

History
During the time of the Ecumene, the galaxy in total had racked up incredible amounts of "debt" due to the scale of the empire's actions.

Concept
When a ship travels through slipspace, it can generate significant damage to the spacetime fabric by creating causality violations and temporal paradoxes. A ship generally disperses this "debt" when exiting slipspace. However, if too much "debt" is created, the ship will be destroyed upon reentry.
