Please help me understand how work card Vestros in Blood? Did it discard all heroes cards from the hands all players, or it puts all heroes cards from the table to discard pile?

I have only russian translation of this card. So I have problem with some keywords.

I think you are referring to the card "Westeros Bleeds"... At the cost of 4 influences it discards FROM PLAY ALL characters. Characters in player hands cannot be influenced by this card

Thanks. You right "Westeros Bleeds" Vesteros in blood - it seems in russian.

Now, its all clear for me.
