Wait.
You mean it actually is painfully obvious that Terran simply doesn't fight wars? It just isn't what we do?
Can we please just go back to the whole "fight monsters and slowly expand into rogue areas" thing? We're good at that.
Absolutely you can. There is this huge rogue area just to your west with some really big monsters for you to fight. Ask Glaumring how to do it. Apparently large archer armies work against small monsters, so perhaps they're effective against large monsters as well.
Kabrinskia won't even stop you or try to invade you in the meantime either.
