Well, good theories really. First off I posted my character name (stupid!)who isn´t random at all but a real Samurai. That might have been cause to take me out which would point to someone very observant/knowledgable about japan history. Ii Naomasa http://en.wikipedia.org/wiki/Ii_Naomasa
Otherwise I come from the totalwar.net site and I´m not really experienced. Players that I remember are Captain Blackadder, Beefy, ATPG, Thermal Mercury.

Obviously this could be used to lead people off track but anyway. Use this info as you like...
