Grey Temple
The Grey Temple is an ideology among necromancers which centers around power and controll. The primary tenants of Grey Temple Necromancy were ownership and domination. Grey Temple necromancers believed that by possessing power over life and death, the very World of Life should belong to them. Grey Temple theology differs greatly from Green Temple specifically around these points.
The Grey Temple started as an ideology. It was never just one temple, but rather a belief system taught by some priests. Later, entire temples would form around Grey Temple philosophy.
History
Durring the Golden and Second ages, necromancy continued to evole. Though Grey Temple theology did exist during the Mage Wars, it was only a philisophical disagreement until the begining of the Third Age. Before then, very few dedicated Grey Temples existed, with most temples following a dual ideology or fully identifying with Green Temple beliefs.
The schism began in the early Third Age as changes in the political climate of the Alliance opened up new lands. Millenia-old disagreements which had little to do with ideology caused many temples to divide.
With nearly all temples now identifying with either Grey or Green Temple theologies, the stage was set for an apocalyptic war.
