You guys are guys are great!
I was totally unaware of these examples but am glad that I wasn't the only one who was intending to use Necromancy as something other than evil.
Who says that army of zombies has to be bad. Perhpas they're just misunderstood!
Heck, there's a lot of what you could consider to be technically necromancy involved in the Catholic faith...and no, I'm NOT talking about Jesus Christ...but think about the Saints...know how someone gets to be a Saint?
Live an exemplary life, or have an exemplary moment of redemption or revelation
Die - usually in the pursuit of holy ideals, or as a martyr at the hands of unbelievers
Perform three miracles...yes...after death
basically, if it can be documented that people have prayed to an individual on at least three different occasions and that something miraculous has occurred afterwards, then that person can be put for to be canonized as a Saint.
We basically appeal to ancestors in the hopes that they'll be more willing to intercede on our behalf than God, who would rather guide us and let us solve our own problems.
And then, once someone is a Saint, different cultures raised in the Catholic faith have their own bizarre list of rituals appealing to said dead people in an attempt to achieve some end...such as burying the statue of a particular saint in the yard, head downward and facing the street in order to have good luck in selling a house...
