Fortress is a card type first introduced in DM-30 Ultra Duel.
When the fortified shield leaves the shield zone, the fortress is put into the graveyard, and the shield the fortress was attached to leaves the shield zone in whatever way it would leave as normal (like being broken or by being put into the graveyard due to Core-Crash Lizard's ability). You can attach more than one fortress to a shield, although some cards can have additional effects when being the only fortress attached to a shield.
