Goo, goo, go away, come again in another four years

[anemoisity]

Clouds have been gathering in the sky once more tonight, and, perfectly on cue, it begins raining at midnight, a torrential downpour of... regular old rainwater? By dawn, the weird slime has all been washed away, leaving Sirocco sparkling clean. Ah, no, excuse me, that's not the sparkle of cleanliness, it's the glint of all those free anemoi the stuff left behind.

((Characters may collect up to 3% worth of anemoi from the event, any attempts to grab more than that will result in the extra anemoi dissolving into flubber and being washed away by the rain.))
