In Alvastia Chronicles, the art used in the Overlord, Orzand character card is pixellated into an 8-bit style and displayed as his in-game portrait.
Alvastia Chronicles is not really a sequel to Journey to Kreisia or Fernz Gate, although Overlord, Orzand has optional dialogue referencing both games. Alvastia Chronicles just has cameos from other Kemco RPGs as playable characters that can be won through premium gacha. In console/PC versions, Overlord, Orzand can also be purchased from the Arena shop in the postgame.
