Final fantasy 8 riddles

[docta fizz]

edit: changing my guess to CC joker during chaos in garden

I'll give you info on your helpers,

gives you gf meter

And even a unique for one of 'em.

holds the leviathon card

You find me in the origin

He's in the garden

And the place for lots of crooks.

he's near where people break curfew

and if I'm way off I should get an "epic fail" sign or something because here comes the next riddle

I decide who lives and dies
bringing men to valhalla
From the break of day
to the eastern archeopaligo
I choose the man who leads the masses
i serve the role of counselor
I can even grant your deepest desire
what am I?
