 * If "Royal Impregnable Fortress" is active, cards/effects that destroy and remove from play cards (such as "Gandora the Dragon of Destruction") cannot be activated. If "Royal Impregnable Fortress" is chained to such an effect, then the affected card(s) is destroyed and sent to the Graveyard, but is not removed from play.
