A fic I'm writing will have pony on pony skirmishes, human on pony skirmishes even a human on human one. Those however will not be the main focus which will be more of zombie-like beings running around both worlds. Would that be multiple themes due to skirmishes or would that be War against others?

While on the topic, and what with the sudden rise in enforcement of the rules: My story has the ponies fight an army consisting of non-ponies, but future chapters will probably include a few (as in three or four tops) pony commanders on the antagonist side. Will that require me to move it to Multiple Themes or can I keep it in War Against Others?

Because the primary focus is not on human or pony warfare, Wars Against Others would be the proper folder.

If the primary focus is on fighting non-ponies or non-humans, this will go into Wars against Others.

Gotcha, that clears it up.
