Hmm.. another reference to tibia, :P In tibia, those type of events are called raids, like, while playing, a message to everyone who is playing would say like, "The orcs are heading towards Venore!" Then about 10 minutes later, it would say,"The first swarm of orcs have breached the castle walls!" and about 100 or so orcs/orc spearman/orc warlords/orc berserkers etc. would spawn in venore. And then it would be repeated twice more, and then the final one would be like,"The last swarm of orcs are being lead by a Banshee!", then hundreds more orcs, and a banshee would spawn in the city.
These events happen weekly/daily, and sometimes 3 in one day. It's fun, but I'm not sure how you would implement it into this game, as it's pokemon, not Tibia.
