Ghost Ship

While on routine parole, the Merlin received a distress call from another Federation Starship. On arrival the ship is found empty and adrift. No bodies, no escape pods missing, no sign of a fight. All engines disabled. While investigating, the Merlin’s engines also go offline and crew start disappearing. Ghostly figures appear and disappear at random. Can those who are left work out what’s happening and save the crews of both ships before it’s too late.
