Eilonwy thought back for a moment before she spoke again. "You'll need to know the first for any of the rest to make sense. As a whole, the branches make a connecting tree tying bloodlines together and relationships. Each branch covers a different collection of who we know as gods but are also figureheads for Prydain as a whole." She started to recall the names of specific figures as she explained things.

"The first covers Pwyll, a prince of Dyfed-- a kingdom in the southwest. In Prydain we call the after life Annwn. It's paradise-- there's everything you'd want, your loved ones, and no one ever gets sick or runs out of food. This is ruled over by King Arawn."

She stopped to sort out the next section but also to give Loki some time to ask questions if he wanted to.
