If You'd like a way more in-depth guide toclassic wow gold everything the Kyrian Covenant provides, Wowhead has you covered there,
But a bunch of angels shepherding the spirits of the dead to where they belong into the Shadowlands is pretty much exactly what I expected from at least one of the covenants in Shadowlands, therefore what pulled me was which characters were chosen to illustrate the covenant's purpose.
Blizzard centered the introduction to the Kyrian covenant around Uther the Lightbringer, who's among the most significant characters in all Warcraft. Not only was that this dude the initial paladin, but he was also the instructor of Arthas Menethil, possibly the most well-known villain in Warcraft history -- you might know him as the Lich King.
In the animation, Uther's soul arrives on the doorstep of this Kyrian at Bastion, as there's some kind of afterlife sorting system that places souls where they belong into the Shadowlands. However, Uther can't let go of his lifetime, and he thirsts for justice. He's chastised for it for a while before Devos, the Paragon watching over him, finds that his spirit is injured from Frostmourne, the Lich King's blade
Now, I could probably enter super-deep detail about why any of this matters, but I will save myself the effort, and you the agony of digging through it. What matters is the runes on Frostmourne are apparently from the Maw, an area of the Shadowlands where only the evilest, irredeemable spirits are cast. And, Arthas, who has caused so much harm, by apparently directing the power of the maw, was cast into that evil place by the soul ofcheap classic gold wow his childhood teacher who died by his blade.
