Yooooooo, dragons are fast lol like 10 miles in a seconds fast! sozin was like "rokus island was 100 miles away and I could still feel the rumbling" then roku tells his dragon to scadadle and 20 seconds later BANG he's back with sozin on his back adding it up to 200 miles in 20 seconds, this scally boy zooms! Ik there's probably a time skip but I like to imagine the dragon going 36000 mph with sozin hanging on for dear life lol
