Magic Positions Chart

This is based on something I found in an old computer folder from mid-1997 for a game concept I was developing at the time. I think my thought was, this would drive the magic system in the game (essentially determining something to the effect of a "sphere of influence.") So imagine that necromancers would fall somewhere between destruction/death and spiritual, druids would fall somewhere over by natural and existance/life, and conjurers/summoners would fall over by creation/birth. All that being said, I'm not sure if I developed it on my own from the way I thought magic should work (at the time), or if I "borrowed heavily" from an outside influence. Does this look familiar to anyone?
