This is Interrogative Book #3.

The Interrogative crew, noted as Seekers hereafter, will enter the Tunnels of Krall at the seventh entrance.
A selection of the crew from the twenty-one surviving Jezo ships, noted as Hunters hereafter, will enter the Tunnels of Krall at the first entrance.
If the Hunters kill all of the Seekers, they win. If all of the surviving Seekers find the first entrance, they win.
The contest will continue until a Seeker win is secured or rendered impossible.
The winning team will be returned to their ship, or ships, and escorted to the edge of Drell space. The losers forfeit all property. The Drell reserve the right to pursue any property on their home worlds, on other ships, or in any other location.
