He just smiles snapping his fingers a chair appears behind her forcefully pushing her towards the board game as she seems to be sitting now across from him. He has full control in his game room. "It's been SO LONG since i've had any visitors.. Twisted sadistic...?" he breaks out into laughter "Child you have no idea who youre dealing with!" yes he can tell she's not a super old her power was strong yes but still left untamed unorganized not at its fullest potential. "But your existence is amusing. Why don't you give it a try you might find you enjoy it. Endless power in your hands."
he offers her his spare dice they aren't ordinary dice though they hold the powers beyond what she's used to a weapon all in themselves.
"The game is simple you roll the dice to decide how far you move one of the figures and pick a card. Their fate is for deities like us to decide!" She can feel he's super malicious but can't exactly read his mind it seems to be protected. The board seems to mimic and change depending on who he selects to move like he is pulling the strings in their actual world from above.
