When Dr Daniel Jackson discovers the location of a lost Ancient laboratory, the temptation to investigate proves impossible to resist...

In the lab, he uncovers a powerful device - a prototype technology designed by the Ancient inventor, Janus, to supersede the Stargate network. But when the Ouroborus device accidentally activates, it strands General O'Neill and his team on a dangerous new world where friends are not always friends and a terrible enemy is stirring.
