Blades of Time

When the once idealistic Vector Prime despaired after the War of the Primes and sealed himself away in a peculiar pocket dimension, he left the Blades of Time in the hands of his comrade Nexus Prime. When assembled correctly, these five pieces of metal are capable of opening a portal to Vector Prime's secret sanctuary.

However, when Nexus Prime split himself into five parts in order to protect the Star Sabre, the Blades were also divvied up, and his five amnesiac components soon lost track of them.
