While seedlings often rise in the cooled ash of a forest fire:
Necromancy is to take the ash and return it to living leaves with no roots, water, or sun.
Some say that necromancy's ban
will always be worked around and that
there will always rise from the cemeteries of history
puppet zombie dictatorships or
extinct species who come back as either invasive or exploited.
At the same time, some say to practice the arts or healing is to practice varying forms of necromancy.
Others cry the slippery slope to inter-life marriage
while simultaneously supporting companies that use zombie labor,
it's all very nasty and complicated, but a very good topic
for your end of term paper.
