The heart of the aspects mount is canon, if you look closely during the dragon soul raid in the last fight vs Deathwing, just as you’re about to finish Deathwing off if you look at the Dragon Soul you can see the heart of the aspects inside of it!
So since this dragon is canon, they should show it more in game, being born from the power of all the aspects combined, he should be fairly powerful.
It’s just part of the beam. I doubt it actually has a mind of its own or a true life force, just an amalgamation of the aspects power being channeled through the Dragon Soul.
As the Dragon Soul is back in it’s own timeline, the Aspects depowered, and the Heart of Aspects dissipated on contact with Deathwing I think it’s gone for good.
I actually bought it one I noticed it in the beam. However, I doubt it’s anything more than a visual representation of the Aspect’s combined power, not a living organism.
There is no evidence of any of that happening. Seeing as how its description says the heart of the aspects was born from the dragon soul, it means its separate from it.
We also never see it again after it hits Deathwing. It doesn’t fly off, it hits him and vanishes, which is typical for a beam attack like the one it was a part of.
Nozdormu specifically mentions the Dragon Soul is back in its time, and the Aspects all make a big deal after the fight to say they’ve lost their Aspect mojo. I doubt they could make another one.
The Players could have extracted the mount from the remains of his chin(that broke off when he exploded into oblivion) that we loot.
if it’s part of lore - they shouldn’t sell it for cash
