These names aren't that original.
Remember once all is said and done and once this is over, you should still have a name that means something, that is creative and says something about your group. Lonely Knights is one such name, Empire of Exiles is another good one.
I for one would like to see your group stay the "Lonely Knights". If Impy wants to fight, let him fight. We all, deep down, are Lonely Knights. I think you have a right to fight for it, we all will agree that those at lonelyknights.cc are Lonely Knights in name only.
