Loopstorm: A temporal eddy, caused in areas that have seen especially high useage of FTL drives, resulting from the fabric of spacetime being worn thin. When a vessel travels through such a region using an FTL drive, there is a chance that it will cause a loopstorm, locking random patches of spacetime into loops that repeat endlessly until the effect dissipates.
These loops cause a severe time dilation effect, either slowing down or speeding up the passage of time relative to normal space. As such, they can cause starship hulls to rapidly age and weather away, or they can trap sensor, systems, or even crew in a loop that can last hours, days, weeks, or even years.
As spacetime damage from unregulated FTL use becomes more pronounced, loopstorms have become more common, more violent, and longer-lasting.
