The subject of random event charts came up on Google+ last week and I thought this might be a good time to look at the yearly, monthly and daily event charts from the original Oriental Adventures.
Most of the annual events look like they would work in nearly any campaign. An isolated realm might not have an actual ambassador visit, but some sort of outsider VIP could become a factor to the game. Tsunamis might need to be replaced if your campaign is entirely inland.
There's not really much on these charts that won't work in an occidental setting.
