Learning Necromancy, Where should I start? Options

Hello everyone, does anyone know any good starting points for learning Necromancy?

I've been researching the topic for a while and I would really like to gain some first hand knowledge. My problem is that the more I read, the more daunting the prospect becomes. Not only do I have to wade through countless pages of RPG nonsense, but when I do come across some genuine information, it seems everyone has their own interpretation of what necromancy actually is and what is involved in its practice. I understand that every practitioner is an individual and so is likely to have their own opinions of the art based on their own experiences but isn't there a 'common ground' if you will, some basic exercises to atleast get me started so I can begin to form my own ideas and enjoy the art for what it can offer?

Any help at all will be greatly appreciated.

I have tried to study this topic a bit myself and it is frustrating as hell dealing with RPG video games. But Necromancy is about communicating with the dead or summoning them. If you are interested in this topic and are open to learning about things in the same essence i would reccomend studying up on some things such as meditating and communicating with astral beings through the art of Astral Projection and walking into the higher realms to possibly speaking with those who have passed as well as gods/godesses. This is just a suggestion on my part i hope you find what you are looking for. Good Luck!

Peace!
