Siguror: Aidan. Dan. Bird. Have we not already had the "appropriate perch" discussion?
Aidan: Yes. And I decided your head was perfect. It's high up and steady and it's attached to you.
I accidentally furry (feathery? woolly?) versions of Sig and Dan.
Aidan is a robin and Siguror is a Manx Loachtan sheep.
They are living in a Robin Hood sort of world/setting.
