How to summon creatures: With a few exceptions, the most common event in many MMOG's is a massive monster spawn. Generally speaking, this chaotic event is officially announced a few days ahead
Break the routine: In every persistant online worlds, you always get used to the pace of things after some time, and don't pay attention to what's around you anymore. These habits often rely on how locations are designed. People run along a path that is more or less the same, from shops to spawn points, etc. Sometimes, these habits can be disrupted. Why don't you shut a popular shop down for some time? You can use any kind of justification: the local trader just married his daughter and went off to the neighbouring town for a while, he has been kidnapped by the competition, he ran away with the money, he died of old age and the shop needs a new shopkeeper... You need to find ways of alterning people's habits, in that case, find a new source of supplies, or try to find out why the shop is closed. Given the GM tools available, you can also disrupt transportation networks and communications, create shortages, make prices rise and fall.
