I'm working on my pShorkyne and the exact composition of the parliament intrigues me. It's barely mentioned in Venarive and the only other piece of Shorkyne canon states, "As of 720, there are 235 members of Parliament. Rarely, however, do more than 150 actually attend."
What catches my eye is the reference to 235 members. While there are 235 esuaren in Shorkyne, no small number of them are held by elgari. In fact, there are only 123 members of Parliament - the 15 malniri who directly hold 127 esuaren and the 108 other esuari.
I can imagine a custom where the elgari also attend Parliament and vote as directed by their liege, but I can't see them being considered full members with the right to (for example) propose legislation and speak in debate. They would really be there to do no more than hold up their edari when it was time to "count the birds".
Another question is how many members must attend for Parliament to function. The custom of a quorum is fifty percent plus one unless otherwise stated (and it isn't). Therefore, 118 esuaren (not esuari or members!) would have to be present for a session of Parliament to commence. A simple majority carries any vote, so in theory, an act of Parliament could pass with as few as 60 votes. Alternately, if the 15 malniri attend, not one more esuari is required in order for there to be a quorum and the business of Parliament to be conducted (and the simple majority vote would be 64). That would significantly impact the political alliances information given in the canon material, and create obvious possibilities for intrigue. (If the Malnir of Someplace is delayed and does not arrive in time to vote, then the king's latest proposal might fail...)
So that's how I see it. I'd be interested in seeing what others think. Also, since I've compiled the list, I'm going to cut and paste the composition of Parliament into my next post in case anyone else might find it useful. :-)
