Conclave is hardly Lawful Good, the three factions were actually created to represent the three chaotic based alignments.
Conclave = Chaotic Good
Circle = Chaotic Neutral
Assembly = Chaotic Evil
The Conclave thinks that humans should be left to their own devices, and play with them, rather than alongside them (circle) or against them (assembly).
If making a human character you don't need opinions on the Three Seelie factions (Conclave/Circle/Assembly), the fact that there even are factions isn't really knowledge that's had. There simply are Seelie. Some of them suck. Some of them seem to be okay.
