Blizzard centered the debut to classic wow gold the Kyrian covenant around Uther the Lightbringer, who is among the most significant characters in all of Warcraft. Not only was this dude the first paladin, but he was also the teacher of Arthas Menethil, possibly the most famous villain in Warcraft history -- you may know him as the Lich King.
In the animation, Uther's soul arrives on the doorstep of the Kyrian in Bastion, as there's some kind of afterlife sorting system which places souls where they belong in the Shadowlands. However, Uther can not forego his lifetime, and he thirsts for justice. He is chastised for it for a while before Devos, the Paragon watching over him, notices that his soul is injured from Frostmourne, the Lich King's blade
I could probably go into super-deep detail about why any of this matters, but I will save myself the effort, and 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 souls are cast. And, Arthas, who has caused so much harm, by seemingly channeling the ability of the maw, was throw into this evil place from the soul of his youth teacher who expired with his own blade.
This is an animation that's totally in the realm of fan service but it's completely working.
I already kind of had an idea that Blizzard would use the fact that we will basically be questing throughout the afterlife to revisit a bunch of older figures, but if that is what we're going to see from that, I am even more enthusiastic. Throughout the storied history of Warcraft within the previous 26 years, there have been a great deal of amazing characters -- both good and buy classic gold wow evil -- which have bit the dust in 1 way or another.
