Well, it was released on limited edition in hardback (you could try ebay or amazon for 2nd hand copies) or a 6-part comic set - which I have. This was released by the Dabel Brothers and I think you can still get them.
It's very good!

Sworn Sword is the second story in the series and was released in a compilation of short stories in a hardback called Legends II which should be available second hand as well.
Happy hunting!
