So quick little info about things to help.
The story starts July 17, 2010 so it's roughly about 4 years after Breaking Dawn takes place.
The OC of I hope you don't mind are:
-Mia Walker (looks like Chloe Moretz) Birthday Sept 19, 1991 so she 18
-Callie Brewers (looks like Danielle Campbell) Birthday Feb 27 1991, Also 18
-Alica Myers (looks like Maia Michell) Birthday Oct 30 1991, Also 18
Breaking Dawn has some young wolves that are never named so here are my ocs of them:
=Caleb Young(Emily's brother)
=Danny Thomas
=Twins; Josh and Johnny Cameron (Cousins of Jared)
=Alex Peterson
They are all 15 years old
=Brandon Clearwater(distant cousin to Leah and Seth)
=Tyler Wilde
They are both 16 years old
The original Wolf pack ages are :
Sam, Emily and Leah are 24.
Jared, Kim and Paul are 20.
Quil, Embry, Jared, are 19
Seth and Colin are 17.
Brady is also 16.
Clarie is 7.
Randoms:
Madelyn is about month old.
Leah husband is Peter Thompson and is 25 with a Quileute mom and a french dad. Peter lived in France with his father during his childhood but came to visit his mom shortly after Breaking Dawn where he met Leah. (She needed a happy story)
And everyone has a birthdays but it seemed a bit much to type just randomly :)
