Caelus and Aero were sitting at the beginning of the magical barrier with their hands conjoined, and their eyes closed. Aero could technically just enter without all of the work, but he alone wouldn't be able to save Nazmi.
Rasne was back at the Red Moon making further preparations and keeping the Queen and her wretched son in line until Samir could come back, so he was unable to help them either.
Samir paced behind the two spell-casters, distraught that his blood magic would be of no use. All he could do was wait.
In child form.
His powers were unhindered by the change in form, but his ego was devastated. He wasn't sure why it bothered him so, but something about going to save Nazmi with Caelus and Aero made him want to look stronger.
Samir wasn't jealous or anything… he just liked to be better than other people, of course. It was natural for a Prince of his caliber and talent.
…
That's what he convinced himself, anyway.
