"Sorcery of Manus, Father of the Abyss. Grant a fleeting will to the Dark of humanity, and volley the result.
The will feels envy, or perhaps love, and despite the inevitable trite and tragic ending, the will sees no alternative, and is driven madly towards its target.". The sorcery probably uses human souls as a volley to hit the enemy.
Parts of this will be speculation, but onto Vinhelm Sorceries. I think their Soul Magic uses Dragon Souls. Three rings, along with the name of the school itself has Dragon in it. I'm especially interested in the Bellowing Dragoncrest Ring.
"A special ring granted to only the most accomplished sorcerers at Vinheim Dragon School.
The ring is engraved with an everlasting dragon, and boosts the strength of sorceries."
Why would it be engraved with the Everlasting Dragon? Do they have some sort of sorcery potential? But that won't work, since Seath developed Sorcery. So thats why I think the school uses Dragon Souls.
Finally, onto Oolacile sorceries. Dusk describes her sorceries as "gentle". I don't really have much else with it. Sorry.
Your thoughts?
