So after watching the animated short again, I was really curious about the scene where Arthas stabs Uther and seemingly his soul is split in two. One half appears claimed by Frostmourne and the other half seems to be with the Light or ascends.
Now, I am not sure if this is to help explain why Uther talks to us from inside Frostmourne in Halls of Reflection but how he appears to his former Blood Elf apprentice in the Plaguelands. Or if this means something deeper like Uther’s soul could not fully be claimed by the Maw or the Light so he ended up in purgatory.
I’m leaning towards the latter because we see Sylvanas get stabbed by Frostmourne it seems to take all of her soul. And knowing this is a weapon of the Maw this is perhaps why she ended up getting damned after the event of the Edge of Night.
So what do you guys think? Was Frostmourne created to send souls to the Maw? If so, is Illidan damned to the Maw as well for being scarred by Frostmourne or does his demonsoul protect him?
