I put this epic checklist together from a walkthrough I had and a disorganized checklist I found elsewhere.  I did fine for a while from those two sources, until I got confused as to what drop was used in conjunction with other drops, and in what order they got turned in.  So, I made a list of all the pieces and sorted them based on the 5 final parts: the two hilts, the two blades, and the scabbard.

The path to take to acquire each of these parts starts at the bottom of each section.  Information on how/where to get the epic drops is listed beside each one.  The details link will fill you in on any additional information/trivia/personal experiences/FAQs related to that drop.  Linked names will give you a bit of information on where to find that particular NPC/mob.
