I Believe this would be a Great place to hear about Cutie Marks. How were they gained, and whatnot.
Icarus' Starts a long time ago...
One Day, While reading from an old Book of Magic, Icarus happened to chance looking out a Window, And Saw a Bird, looking intently, before turning and flying off. then, Icarus Knew, He had to at least try Flying. Later that Afternoon, Wearing what appeared to be a Simple Kite Strapped to his back, Icarus Stood on the Roof of his old home. "W-Wings... C-Check. W-Windspeed... B-Blowing. R-Roof... b-being a r-roof. W-We're a-all set!" the Young Colt Said Bravely, Mentally Preparing himself to jump off. With a running start, Iccy Flew... And, A Strong Gust of wind Snapped the Already Stressed Branch holding the Glider together, and Icarus tumbled to the ground, a CRACK Sounding as he fell.
Two days later, one of Icarus' Legs was Wrapped up in a cast, but, throwing the Covers aside, his Cutie Mark Was There!
FUN FACT: depending on the Age of the Main six, That Gust of Wind can be Replaced by a Wave of Chromatic Energy!
