Celtic Tales: The Saga of Cairn

This is a simple, but interesting and exciting story in a Celtic setting. The premise is this: you are a young orphan named Cairn, living in the Celtic settlement of Rath Druim-Eir, in the center of Ireland, and you are a blacksmith's assistant. You also have two friends who often follow you around, Einid ingen Fionn, the daughter of the elder warrior, and Maeli ingen Beigann, the daughter of the chief druid. This story can be whatever YOU write it, so enjoy the exciting (hopefully) adventure! :) P.S. I don't understand history and know little about those times, so if you find any mistakes, inaccuracies, or anything like that, I'll be glad to receive comments and corrections. I hope you'll like this story:)
