Thanks for updating. This the only other info. I know about the Sand Sibs.

These are their ages for the Chuunin exams. I think after the first time skip, they're 14, 15, and 16. And I think after the second one they're 16, 17, and 18. Update again when you can.

The San Sibs are all a year apart. Temari is the oldest, Gaara is the youngest, and Kankurou is in between. Sorry, I don't know the year Temari graduated the academy. I liked your first chapter of this fic. Please update soon.

It's a relly great start. Can't wait 'till the next chapter! ^.^
