In addition to the Galactic Senate, United Galactic Council and Metaverse Republic Senate I propose the "Senate of the Galactic Republic". This should clear things up nicely.
Excellent! Get that thread started right away.
We of the Galactic Senate offer peace in exchange for all of your planets, money and influence
Deal! So....we have no planets, money, or influence. What we do have is one dusty multi-purpose room that we rent, some cardboard tables, folding chairs, stale donuts, and empty filing cabinets. You are now the proud owner of all the aforementioned items. Congratulations!
Sentient species taste better...
