Didn't Jace send out 'Walkers to hunt him down in the video game? (Waybe not to kill him, but at least "stop" him?)
Are the video games canon? I have legitimately no idea at this point.
That part is confirmed by some of the short stories, so it must be. There was that cryomancer who had his skull split by Garruk's axe for instance, and later Jace showed up and agreed to stop bothering Garruk. In another story, Ob Nixilis vaguely references the young planeswalker who took the hedron from him, and the part where Jace was behind that might be referenced briefly in BFZ block when Jace recognises Ob, but I'm not entirely sure about that last point. Vraska is also aware of Garruk's condition and of Jace's part in the affair.
I basically agree with Raven, I think Garruk's curse is perfect as the boomerang that comes back the long way around and hits the Gatewatch hard. We don't know how the Chain Veil arc in general is going to be resolved, though, that might affect Garruk and possibly Ob Nixilis as well. Whatever the case, I really hope Garruk just gets cured and goes back to being his old
self rather than being killed off. I liked the old Garruk a lot. If nothing else, he could mentor Domri to give him something to do (and teach the kid some manners in the process). Or, I don't know, get into an epic fight with Kiora. Just about anything as long as they explore his old character more. I also have a very soft spot for his origin story in the webcomics, that really helps you understand how Garruk became the way he is (well,
was). Would be cool if the hedron was removed and he got worse before getting better, though. I want to see a demonified version of him, like they did when they retroactively tied
Ob Nixilis of the Black Oath's armour to his look as a demon. Garruk already has tusks on his helm, that would give them something to work with. 'Garruk, Demon of the Hunt'...
That said, if he joins the Gatewatch somewhere down the line, especially if Lili is still there at the time, I might just give up on the Magic story altogether...
They'll just retcon the curse and pretend it was someone other than Liliana who did it. It'll be fine.
It'll be fine. It'll be fine.
