my prediction

[Bob]

I think that it will be chaos in the multiverse after Apocolypse, and it will center around Barrin(or I hope in centers around Barrin) who had the spark, and ascended when he blew up Tolaria.

Barrin will take a vacation in Planeshift, traveling from plane to plane, and no Dominarian knows he's a walker.

The bad guys will be followers of Tevesh Tzat, the BOT.(Brotherhood of Tevesh) who worship Tev as a god, and are as insane as their god.

Another cool scenario would be Urza losing his powers, though I doubt it. Mortal Urza would be cool

 

[Bob]

Darigaaz dies in Planeshift. he was the one who was "terminated"

 

[Azreal the Soulmaster]

doesn't tvesh szat have something to do with his demise

 

[MrXarvox]

Szat corrupted Darigaaz through sorcery and made him power-hungry. When Darigaaz's conscience caught up with him, he sacrificed himself to weaken the insanely powerful group of the invasion dragon legends (himself included) who were wreaking havok on all non-dragon species and some dragons too.
