Haven: Call of the King

The King Athellion has left his homeworld to fight in an intergalactic crusade. He left behind a huge bell - The Golden Voice - for his people to call him should they ever be in danger.

During his absence however, the evil Lord Vetch invades the planet and enslaves Athellion's people by infecting them with a deadly virus. A virus, that requires a constant treatment with an antidote called catana.
