There are several Knights, armored figures, and atleast one Wizzard in The Marketplace here (as well as many of the other on-line stores around the net). DAZ (http://www.daz3d.com) has a dragon and so does Anton over at BBAY (http://www.bbay.com).

If you don't have any money at all to shell out there is at a Wyvern here: http://poseworks.posermail.com/characters/ and I think that LordWarrior's knight is at PropsGuild.com. I haven't seen a complete King figure, you may have to mix and match from other characters.

Hope this helps.
