Urza's Saga

Urza's Saga are the remnants of devices and magical artifacts that Urza left behind to aid in the repairing of time rifts, should any recurrence after the great mending take place.

After the great mending that cured the multiverse of time rifts, it is unclear whether these devices working in concert would serve a greater purpose any longer, but they still lie scattered across the multiverse to be discovered.

It is said that time rifts are the universe's backlash against deicide, nature abhors a vacuum, though none have been seen or felt in millennia, there was a threat of a rift re-opening some few hundred years ago; perhaps that is why Urza's saga now reveals itself.
