Deep within the darkness of Ulgu, Realm of Shadows, lies an impossible maze sequestered far beneath the sea. Two warbands brave the twisting shadow-magics of this ancient place, one spurred by divine decree and the other by selfish rapacity. Success may mean escape and survival, but few return from Harrowdeep – the nightmare abyss where light itself withers and dies. Enter the ultimate competitive miniatures game with the Warhammer Underworlds: Harrowdeep Core Set. Inside, you'll find everything you need to start gaming below the waves of the Shadowsea, with miniatures, dice, cards, and more. Harrowdeep marks the beginning of season five of Warhammer Underworlds – a fast-paced, deck-based skirmish game set in the Mortal Realms. You can play right out of the box using the pre-built decks for the Rivals format – which is new to this season – or you can hone your deck using cards from the Warhammer Underworlds card pool for a strategic challenge. —description from publisher NOTE: The card back graphics in this set do not match those of all the previous games released in the Warhammer: Underworld series. You will not be able to mix and match cards from other previous sets with this one to deck build a unique team.
