RPGaDay #25: Calamity

For #RPGaDay2019, the twenty-fifth word prompt is Calamity.

       
        The biggest calamity in a game I played was the ancient slumber dragon awakening and destroying the world in #DungeonsandDragons (see Day 6: Ancient).
        The flood that wiped out our group in #Earthdawn after we took shelter in a house on a bluff for seven days as the waters rose to drown us was one of the longest calamities. I guess we should have turned the house into an ark! This is also the premise of #50Fathoms, but at a much slower rate.
        The avalanche that wiped out the group in Earthdawn was the biggest calamity in a game I was game mastering (see Day 16: Dream).
       The biggest calamity that never came to pass was me trying to tame the Tarrasque and use it to destroy all civilization (see Day 7: Familiar).
