Forgeworld Wraithseer (http://www.forgeworld.co.uk/Events/Wraithseer.html) is a conversion set to warlock-ify the plastic Wraithlord.
I'd call this model pretty excellent frankly. The Wraithlord model is great as-is for introducing Wraithguard as NPC nasties, so a "named" psychic Wraithguard would be even more fun :P

In other news, FW have also unveiled the Eldar Corsair (http://www.forgeworld.co.uk/Events/Corsairs.html) conversion pack, which while it has no direct use for Inq, still serves as good inspiration for non-craftworld Eldar projects.
This is a very great model ;D
It is a good-looking model, he could certainly find some use.
