Chattan

Chattan is a member of Sluagh, brother of Iomhair and cousin to King Sholto.

Swallowing Darkness
 Chattan and Iomhair areon guard outside Sholto's room when Meredith arrives with a  wounded Mistral. Both brothers are polite and appreciate Meredith's politeness. Chattan asks if she is really pregnant with Sholto's child. Meredith confirms it and feels the conversation was important.

 Chattan is again guarding doors to Sholto's room when Meredith and the rest get out of the garden. This time, he is paired  with his uncle Tarlach, a nightflyer.

 Meredith convinces them she needs to use a phone to call humans and get the Seelie to leave the outside of Sluagh sithen. On the way to the phone, however, she feels the need to help Sholto and despite being warned by both Chattan and Tarlach that she looks too sidhe to help their King, she opens a way to the chamber of decision.

Meredith wonders if possibly Ivar or Fyfe was Iomhair's and Chattan's father.
