The grand banquet of the Fae is actually another term for the 'Fae Grand Meeting,' a significant event to decide the future course of actions for a local Fae tribe.
That's what it's called, but expecting a group of Fae to sit quietly in a conference hall, following the rules of 'you propose, I agree, then we vote' is impossible.
Just as Dwarves make their most important decisions at the dining table, and Elves always decide while sipping tea, Fae simply cannot accomplish anything without holding a lively, celebratory banquet.
Before Hua'an and Frost Butterfly returned, the Primal Fae didn't possess much wisdom, and their forms resembled tiny mosaicked butterflies... or perhaps oversized moths.
The smartest among them was Frost Butterfly herself, vaguely humanoid with slight intelligence.
But even then, not much.
