Since the Transpace Jumpdrive exists, consider making a ship that uses it. Suppose that the Penitents have a single ship called the Penitent Striker, which warps in when a Monastery is under attack and warps out when it is badly damaged (e.g. more than 50%) or when the enemy leaves. If the player destroys this ship with a sufficiently powerful blast, they are guaranteed to find a Transpace Jumpdrive in the wreck.
