Me would like to first state, me hope there is a variety of non-clan factions outside of Nezumi. Like Naga or Ronin or Fudo or Madness. However this thread be bout how we can bring Nezumi back to the public eye. Try and be friendly yet civil. Let us begin.
Me personally would like to bring back Nezumi in future set as LCG be perfect format to bring them back. They weren't a horrible faction, far from it. Nezumi were a faction that won many koteis and became fan-favorite. Only problem was we originated as a "joke faction" so no one really took us seriously.
The plight of the "Last Tribe" is ideal in reality for Nezumi. It not only one of drama, but people tend love that group or faction that seem to be last of their kind. Way of The Ratling is a good book to read, it talks about not only the mechanical side but the flavor side of Nezumi. Good example of this:
"The idea that things happen by chance is an astonishing new concept that had simply never occurred to Nezumi, and appeals greatly to many. Nezumi stand in awe of people or things that appear to be lucky.
As humans first introduced the idea of luck, they are thought to be extremely lucky. Obviously it is luck that has given the humans their power and wealth. Luck allows humans to live a long time, makes their steel sharper, and makes spirits obey their will. Everything that a humans do that a Nezumi cannot is often attributed to luck. A few Nezumi have embarked on quests to find the source of luck, to steal it or destroy it, with no success. The xenophobic Green-Green-White Tribe has taken a more direct approach, and carry the skulls of dead humans as good luck charms.
