Whirlpool entity

A massive consciousness in the form of a swirling whirlpool that suddenly appeared in a relatively empty sector between Starbase 73 and Endicor in 2365. It had a tractor-like pull that holds the U.S.S. Enterprise NCC-1701-D, at even Warp 9, and threatens to destroy the ship over and over in an endless Moebius loop of time.
