Deep underground the capital city of Kostos exists a decaying system of labyrinthine tunnels, abandoned buildings and overflowing sewers. In this forgotten world, known as the Graveyard, a gang of abandoned children fight to expose the ruler of Kostos, the Kai, as the monster he really is. Using any tools they can, the group turns to a mysterious elixir to heighten their powers. The price? A shortened life. The serum destroys their body as soon as they reach maturity.

Javin and the Haunt follows Javin as he searches for his little brother and falls deep into this underground world. He must ask himself what is more important: a brutal, short life of power and change? Or a long one filled with memories of those you lost and never helped?
