Necromancy

The forces of purity and corruption, nature and taint, are present in the forces of light and shadow. Shadow energy is the stuff of Necromancy, allowing the dead to be raised as mindless warriors and lives to be cut short with dark power.

Necromancy is not necessarily "evil" but is generally frowned upon because of the dark and corrupting effects of using such magics. Necromancy is anathema to the natural order, and this is ever-present in the effects it has on living creatures who attempt to use it.
