While I'm usually keeping things here game mechanic free, I'm running this world w/ the Pathfinder system for now. It was originally designed with D&D 3.0 / 3.5 in mind with a heavy influence by Ars Magica 4.0.
For the Jutelands, I'm borrowing a list of deities that I found on a Pazio message board - at least until I can find or create something better.
Aengus (god of love and beauty): Charm, Luck, Trickery
Arawn (god of the dead): Darkness, Death, Repose
Brigid (goddess of smithing and healing): Artifice, Fire, Healing
