* Severn murdered the two children they had taken in while they were in the fiefs. Severn did this to protect Kaylin so she could not be used by the Outcaste Dragon. He is the only Dragon that has ever been outcaste. We learn later why he eventually became one. If the two children had been marked and killed, Kaylin could be used by the Outcaste.
** Severn came to the Hawklord's office and Kaylin attacks him on sight. She doesn't really try to kill him but later, when he is in the Foundling hall, she actually does try to kill him because she is afraid that he would kill the children. Children are precious to Kaylin and she is very protective of any child.
