From the animation, Uther's soul is located on the doorstep of WOW Classic TBC Gold this Kyrian at Bastion, since there's some kind of afterlife sorting system which places souls where they belong in the Shadowlands. However, Uther can not let go of his life, and he thirsts for justice. He is chastised for it for a while before Devos, the Paragon watching him over, finds that his soul is injured from Frostmourne, the Lich King's blade
Now, I could probably go into super-deep detail about why any of this matters, but I will save myself the effort, and also you the agony of digging it. What matters is the runes on Frostmourne are apparently from the Maw, an area of the Shadowlands where only the most wicked, irredeemable spirits are cast. And, Arthas, that has caused so much harm, by seemingly channeling the ability of this maw, was cast into that wicked place by the spirit of his youth teacher who expired with his blade.
This is an animation that is totally in the world of fan service but it's totally working. It is not just a secret that I'm chomping at the bit to receive my hands on World of Warcraft: Shadowlands -- I was already sold by the Vampires.
I kind of had a notion that Blizzard would be using the fact that we will essentially be questing throughout the afterlife to revisit a bunch of older characters, but if that really is what we're likely to see from this, I'm even more enthusiastic. Throughout the history of Warcraft within the previous 26 years, there are a great deal of amazing personalities -- both good and bad -- which have bit the dust in one manner or another.
I haven't been playing these games since their beginning, I'm not old enough, but I have been playing long enough to get a load of sentimental attachment to a lot of characters, especially ones which are no longer with us. Shadowlands is only two months away at this time, and I can't wait to go in and get my hands on it. There are a great deal of dead characters I would love to watch again, and when the Bastion animation is anything to go by, it seems like I will get that wish. I just have to buy WOW Burning Crusade Classic Gold wait a bit longer.
