Perhaps the oldest and most controversial school of magic, Necromancy allows magic users to assert control over the very nature of life and death.
Necromancers are a rare breed of pariahs, mad scientists, and reanimators who use their powers to raise armies of shambling zombies, spread malignant diseases, and drag souls back from beyond the veil.
They can obviously raise the dead, but can also toy with the life force of others in more subtle ways, and are particularly adept at all magic that concerns domination, imprisonment, or destruction of the soul.
There are many different ways to reach beyond the veil of death.
