Adrenaline coursing through his body, Beni once more opens the link between his spirit and the Realms Beyond. Taking a rune stone in hand, he leaps backward from the scrum and begins to dance to a rhythm pulsing in his ears alone. As he swings his foot in a wide circle around him, a network of sigils erupts from the ground where it passes. "O creature whose heart is bound to mine own ..." His unspoken prayer activates the glyphs and opens the gateway for Ven'nyar, Avatar of Winds, to manifest.

I dunno. Sort of extrapolating off of Final Fantasy X's concept where Yuna twirls her staff and dances to manipulate the spirits around her. Also Foxtober, I guess, since Beni is a Renjin (kinda arctic fox-ish).
