I wonder what uglu verison of necromancy could be. My guess is hyper-realistic reality bending nightmarish illusions. And/or living shadow monsters
Necromancy is Dhar used through Shyish. Its about the denial and perversion of Death where Shyish is the embracing and acceptance of Death.
So we can apply the Wind filter:
-Ulgu
-- About dreams, mysteries and boundaries. Its transient, about what people think of something rather than the reality behind it.
--It plays with boundaries, looking beautiful or ugly. Turning one kind of edge into another.
--Funny really, given how the Grey Order prides themselves as a Practical school of magic, but then you need your feet on the ground to have your head in the clouds safely. Not so different from Hysh after all.
--Dhar-Through-Ulgu - So, what is the most twisted interpretation of Shadow possible based on the above definition?
"I am the Shadow, the True Self."
Make all dreams come true.
All of them. Especially the nightmares.
Granted its part of College traditions that you should not attempt to become the second Nagash.
