How do you, like, conquer a territory?

It is effectively exerting one's control, presence, and influence over a dimensional region. Typically, the owner of the territory will defend it and attempt to prevent a takeover. The more territory you have, the more strength you likely have at your disposal. Of course, you could run out if in nonstop battles, but for the most part, that's how it works.
