Sidar Kondo! Gerrard Capashen’s adoptive father! Hails from the land of Jamuraa and was given flanking to reflect this fact. After his true son Vuel failed a rite of passage, Sidar disowned him. This unleashed all of Vuel’s hatred and contempt and started him down the path to becoming one of early Magic’s more well known villains, Volrath.

Kraum? That’s a new one. Ludevic however, is a name any fan of Innistrad should know. The necro-alchemist is responsible for a menagerie of abominations that terrorize the plane, and has recently been seen tutoring the young but promising Geralf Cecani.

Silas Renn was Tezzeret’s rival back in Esper. Constantly overperforming the planeswalker at the Academy of the Seekers, Renn’s talents are only outshone by his nearly entirely-made-of-etherium body. Even his heart is shiny new etherium! Nicol Bolas allegedly devoured young Silas in Test of Metal, but the canonity of that novel is…far less than credible.

Bruse Tarl is unexpected but entirely welcome! Bruse is a herder from Goma Fada known for his dealings with the ornery domesticated animals of Zendikar. His Pillarfield Oxen are easily his most famous charges.

“May starving fleas birth a thousand generations on your stubborn hide, cow!”

And then there's Atraxa I know she's an Akroma-esque salad of keywords, but still, look at her!

She compleats me...

Maybe it's the same plane as Second Wind. "Vindr" is a very nordic form, which would fit with Valla and Immersturm.

I'd bet the Immersturm is, as the name suggests, some sort of Storm. Maybe a literal eternal-war-storm that crawls over the plane constantly reshaping political and geographical boundaries by destroying what's before it and leaving the place new (if a bit wrecked) in its wake. So like the Roil, except it's all concentrated into one (moving) spot and the locals have decided it's fun.

So, what is going on here. Is Silas airbrushing his bots?
