The pegasus-run weather bureau in Cloudsdale does a great job in keeping Equestria's weather under control, but sometimes you get what are known as "Rogue Storms" which are bigger, wilder or more powerful than the norm. When this happens the Royal Equestria Rogue Weather Control Team known as "The Storm-Riders" rise to the challenge.

Sirocco, mistress of alll desert storm phenomonon, is a strange pony no matter how you slice it.
Heralding from a region she refers to as The Great Dune Sea she left everything she called home after what she called a "Too-much-was-understooding". Traveling to Equestria she was lucky to fall in with the Storm-Riders who accept her for her quiet, introspective demenor and unfortunate (but often funny) mangling of adages.
She gets along with the team very well, concidering them the family she should have been born with instead of the ones she did. Also lately it has come to light that she has a very keen mind when it comes to numbers and the Equestria tax-code.

Sirocco comes from a story that Werekitty http://www.furaffinity.net/user/werekitty39501/ and I have been working on. "The Sour Grapes Chronicles" http://www.fimfiction.net/story/710.....pes-Chronicles follows the life and adventures of the owner of a modest Vineyard across from Sweet Apple Acres. Often she reacts to the events of the main series and has her own little adventures that happen "off-camera".

Sirocco was a little harder to pin down as Werekitty and I have always pictured her as being remnicent of Arabian horses. After some introspective on the first picture Bloodoodles http://www.furaffinity.net/user/bloodoodles/ made an adjustment to her muzzle that set her apart from the average pony and really brought out her exotic nature more.
