Paracosm
Normally, the flight to work is a half-hour. Wyvernbight's thermals aren't very strong, and I'm not exactly the most graceful of beasts, but I can get from one spot to another without too much hassle.
When it rains, though, the skies become sodden spans of unpleasantness. Flying in the rain with dedicated ritual gear guarantees either four times the travel time or something not surviving the trip. I'm grateful for the carriers in these times, but Great Work are they cramped.
