In an exploration mission across the galaxy, a spacecraft suddenly lost communication with the Etherean Empire control base. The last signal report showed the spacecraft hovering nearby a black hole on the night of October 31st. Invader Krool was the only soldier aboard that unit, and it was the last time anybody heard from him. Legend has it that every night on the day he went missing, Invader Krool would roam the corridors of the main citadel looking to exact a spiteful vengeance over those who failed to bring him back to Planet Crypto.
