Um... you don't?
Ask your DM if your character is going to have to deal with this problem on the regular and, if you are, you either come up with a solution (e.g. leaving the undead horde in a ditch outside of town) or you don't play a necromancer.Necromancers are cool. How do you play one without getting drummed out of town by peasants with torches and paladins with pitchforks?
I wonder if a society that worships their ancestors as warriors who protect them might see necromancy as part of their culture. Perhaps even to the point where remains are seen as tools of defense and not sacred as they are in many other cultures.I could see an isolated event like a town being attacked by orcs or something and the local mage raises the undead army to repel the orcs. The town may not like grandpa being raised, but should like it better than the orcs killing them. After the necromancer saves the town? Who knows how the folk will react to him.
Venture Bros Wiki said:“Dr. Orpheus is an expert necromancer... He is headstrong, tends to be unaware of the perils of most situations, and is quite melodramatic even in everyday situations. He has quite a large, extensive vocabulary he freely uses, though his theatrics tend to spill over into his more everyday activities, such as offering a snack of pizza rolls with an unnecessarily dramatic flourish, or warning people away from the bathroom because he had Taco Bell for lunch. Orpheus' actions and speech are usually accompanied within the show by overly suspenseful string music which adds to his campy, over-the-top presentation. Unlike some more conventional characters, Dr. Orpheus sometimes uses his great powers in very mundane ways; he can be seen using telekinesis to help prepare dinner in the episode Ghosts of the Sargasso. He seems to be somewhat self-conscious of the fact that despite his abilities, he leads a rather ordinary life. Perhaps this is best illustrated by his proclamation that although he only holds a Bachelor's Degree in communications from a community college (with a minor in women's studies), he has been granted a Doctorate from "a higher power than a mere college professor" - his master admits Orpheus is his "greatest student". Dr. Orpheus mentions in that he teaches "conjuring" at The New School.
Despite his initially imposing necromancer persona, Orpheus is actually one of the more benevolent and morally balanced characters in the series, as contrasted with the cynical and amoral Dr. Venture. He is helpful, pleasant, and genuinely cares about people. He also acknowledges his job is to help preserve the fabric of reality from supernatural forces, suggesting that he has given up a normal life (which he seems to desire) in order to serve others.
