This looks cool, I like your backstory too
i really wanted to make a human paladin with sw gear :< but its hard to get any pieces that may look like it
Try and get as much basic plate or silver mail as you can (Platemail, Augmented Chain ect.) But if you just want to look like a clone try the Imperial Plate set. That's what most people wear.
This gives me the Warcraft 3 feeling... Soldiers walking with their giant shields... It's nice O_O I was going to ask if this was a screenshot. xD
