As I understand it, real-life wormhole physics gives enormous advantages to a defender. However, this is a wargame, so I will have to limit that somewhat. Exactly how, and to what degree - well, that's something I will be confronting in a year or two.

(And yes, it could be weaponized. Doing so might not be a good idea, depending on the lovecraft parameter, but you can certainly try.)
