STeMS, or Short Term Minnow Syndrome is a metadisease that can strike at any time. It afflicts only Imperium Nova players, and strikes most often at the very old or the very young. Symptoms include forum inactivity, a failure to send or answer PMs, neglect of House finances, and in the terminal stages, the timing out and deletion of the player's House. As the name implies, new players are particularly vulnerable to this disease, often proceeding straight to the terminal stages if infected within a single login. More experienced players tend to avoid the terminal effects, but may instead become afflicted with a highly-morbid but minimally-mortal variant known as Silent Giant Disease, often as a side effect of the Real Life.
