On his quest to find the human possessing Net Terminal Genes, Killy embarks on a journey full of action-adventure and dark discovery before entering Cluster Town. Killy comes across a woman who offers her help. Her vast knowledge of the power behind this city proves to be an asset to Killy in more than one way. As they attempt to break through to the sector above, the Authority - the network that makes up the "brain" of the city - stops them. Will this mean the end of Killy and his search? Is there still hope for the last of the dying human settlements?
