Skandar and the Unicorn Thief/Phantom Rider OC Insert

I made a Skandar fanfiction... Because I'm delulu... The characters (other than my OC's) belong to A.F. Steadman.
Anyways, my OC's name is Estelle. Her brother's name is Aster. They're twins, and they both become riders. Estelle is a fire wielder and Aster is a air wielder. Oh and Aster is a silver. I made other OC's, but you'll find out about them later. Also Estelle enters the Eyrie a year later than Skandar, so she's a Hatchling during Phantom Rider.
My grammar sucks but I don't care :p
lmao okie! if you like this premise, then you could read this. bye pooks!!!
