Well you have two Cid's Knights (one current, one former!) on that list so it's hardly a list of the obscure!

We have Odd-Eye, Hardwood Hank (I think - the letters spell Hardwood Hhonk), Recirculatory System, PureMourning and JackNapier.

The letters we have unravel as Loony BoB's Wedding Paety which I can only assume means his Wedding Party.

PureMourning was the tricky one. The other four are all better known by other user names.
