The League of Laws is an inter-clan council.

Yes, having only one representative is too few. The ideal option is two, if there will be a secretariat, and three, if there will be two chambers. I believe that both have their advantages. In the first option, there is efficiency (the secretariat is small). In the second, there is representativeness (the interests of a larger number are taken into account).
In general, I would like to hear from the clan leaders whether they are ready to join the League of Mapmakers and Modders (LZMS)? I am.
We can create it first, and approve the charter at the first session of the LZMS.
