I don't think it's that kind of fairy queen.
Siam`s gonna be the witness
To the ultimate test of cerebral fitness
This grips me more than would a
Muddy old river or reclining Buddha
And thank God I`m only watching the game -- controlling it --
I don`t see you guys rating
The kind of mate I`m contemplating
I`d let you watch, I would invite you
But the queens we use would not excite you
It might be a bit too cliche, but perhaps the egg of a dragon? Not just ANY dragon though, but Huhumihuhu, a Fairy Dragon. On the plane of Arborea (or Feywild). Good luck!
And thus "Alice Through the Looking Glass" meets "70's acid trip". Good luck, adventurers!
Play some Zeppelin and/or the Beatles in the background, but try and find the songs without the lyrics...
2 nice pieces of psychedelia are the intro to "In A Gadda Da Vita" and the extended version of "Susie Q." Also look at early Pink Floyd and ESPECIALLY the early works of Tangerine Dream- trust me, there is nothing more consistently trippy than that band's first few albums.
Re: Marriage.
The marriage does NOT have to be to Queen Mab. It could be to one of her relatives or supporters as a reward if mortal mates are "in" this century.
Or, if she's trying to embarrass someone in her court, pairing them off with the least charming and/or clumsiest member of the party would be a huge slap in the face..."A pairing of 'Princess Beauty' with Sir Beast, hahahahaha!"
Re: Service
She's a queen, she'll need champions. Champions, being a depletable resource, requires the choosing of new ones. And as mere mortals, Mab will feel zero compunctions about moving them to the front of the duty list.
