Equilor

Equilor was one of the most ancient and distant planes in the Multiverse. According to Urza, it was the most ancient plane, from the "edge of time". Everything on that plane appears "fallow" and "spent". Not much is known about this plane, as the only account of it was Urza's visit. Almost all that is known about Equilor is from the novel Planeswalker.

Description
The plane was inhabited by powerful beings, who were seemingly human. It is not known if they were planeswalkers, or just a civilization that developed powerful magic. They claimed that Urza found them only because they allowed him to do so. Supposedly, their magic could The Eon Fog. They also had much insight on other planes in the Multiverse. The people there also appear to have overcome their desire for greatness, and even boredom itself. The Equilorians supposedly began their search for enlightenment in -100,000 AR. The mountains on Equilor are flatter than most mountains, and look as though they were flattened only by time. A never-lifting mist known as the Eon Fog exists on the plane. A notable location is Bloodhill Bastion, a city on a hill that seemingly is created from living tissue. Sphinx-like creatures are guarding it.

Urza's visit
During the period of the Shard, Urza traveled there in hopes of discovering the origin of the Phyrexians. The elders, mysterious spirits that live in caves in the mountains of that plane, told him that the Phyrexians couldn't reach Dominaria because of the Shard of the Twelve Worlds. They also cautioned him that Dominia (the Multiverse) is full of dark forces like Phyrexia, but that they will fall eventually. He talked about a great many other things as well, and was in the mountains with the elders for nearly forty days at a time. Calmed by the revelations of the Equilorians and the splendor of the place, Urza decided to stay on Equilor. He was amazed by the knowledge the people of the world had gathered along its eons of existence, and was also astonished that the Equilorians left it almost unused. Urza quickly devised many ways to employ it, and wished to change Equilor into a mechanical paradise, but his intrusive plans weren't received well by the majority of the elders. Fortunately, Urza soon had to leave their home plane. The Shard had been destroyed, which again left Dominaria unprotected from Phyrexian forces. Once the elders told him of this, Urza planeswalked away to prepare Dominaria for certain invasion, never to return to Equilor. It took Urza a hundred years to planeswalk back to Dominaria.
