Perhaps Weaver had a strong soul, but I feel AA is stronger as an ancient elemental being.
What makes you think a spirit had no mortal impersonation before?
They are spirits. They think, they act and they fight. But spirits are the creation of the mortal minds, while souls are the heart.
No spirit is born without a mastermind behind it.
And if that so called mastermind is dead, the spirit may exists further without body. AA is no excuse.
