Can you guess what they do?
What do they train?
I can guess Primeval makes Dinissaus units, but we already have a Temple that makes Archons.
The Pantheon Temple is the 'base' alignment Temple. After capturing a Pantheon Temple, the player can change it into a Celestial, Primeval or Infernal Temple depending on their hero's alignment - Celestial if good, Primeval if neutral and Infernal if evil. If a neutral or evil hero manages to convert a Celestial Temple, they will be unable to produce anything from it and must change it to the Temple of same alignment before they can make use of it (same for the Primeval and Infernal Temples). All three of the alignment Temples produce units, similar to vanilla.
This will cause some issues with some map strategies, when you actually want to produce Archons or Daemons.
There will be less of a problem in 0.9 since it won't matter as much (unit types take precedence over damage types).
