This model of Krondys Son of Dracothion was at Warhammer World.
Long before the great drake Dracothion rescued Sigmar from the void, the majestic Draconith empire was utterly shattered by the cataclysmic fury of Kragnos. The God of Earthquakes laid waste to their grand cities one by one, leaving only a tragic remnant of their proud species alive. Unable to slay the immortal beast, the dragon princes Krondys and Karazai turned to the enigmatic Lord Kroak in a desperate bid to seal their nemesis beneath a mountain. There Kragnos remained entombed for aeons—until the magical shockwave of the Necroquake ruptured his prison. Now, with the Earthshaker unleashed once more, the Draconith princes have bound their fate to Sigmar through the sacred Pact Draconis, leading a fierce new generation of dragons to war in defence of the Mortal Realms.
