or a real, serious threat that causes realms to shrink.
If that is the case, then it should be a short-term surge of monster spawns that quickly shrink realms and is over within two or three weeks.
If spawn rates are brought to this level on the long term, then realms will do nothing but fight monsters and will be incapable of going to war against player-controlled realms. The beginning of Dwilight allowed for fun RP while people were establishing the realms' cultures and colonized the land, but there were very few wars.
