Necromancy

The forbidden art (justifiably so?)

Necromancy is a controversial school of magic. While there are dark practitioners, raising undead minions to do their dark bidding, there are also practitioners that use necromancy for good.
Many nations recognize this and allow its citizens to practice necromancy. Others ban it, punishable by fines or even death.
Practising the art

Part of the reason that necromancy is disliked is due to the nature of it. In order to resurrect the dead, the practitioner must delve into the life force of the planet itself - the well of souls. The spirit of everything that dies returns to the well, giving life to the planet. When tapping into the well, the practitioner will need to find the spirit of the individual they wish to resurrect and pluck them. At this stage, the practitioner can begin the process of rebinding the soul to its body. The remainder of the reason necromancy is disliked is due to the aftermath. More often than not, the individual is not the same when resurrected. At best, the individual is brought back with serious mental scars (such as PTSD), and at worse they are a shambling husk. To ensure the best result, the practitioner must follow the following rules;
1. Resurrect the individual as close to death as possible. The longer the spirit is held within the well of souls, the more the spirit will be broken down into energy.
2. Ensure the corpse is complete. Even a missing tooth could turn the resurrected into a husk.
3. Do not allow the ritual of resurrection to be disturbed. The ritual breaks the spirit down to bind it into the body. Interruptions may cause fracturing.
4. The ritual must be completed under the moonlight. Solar energy energises the spirit, and makes it harder to bind.

There are rare stories of individuals being resurrected exactly as the day they died, but these cases are few and far between.
