In 2367, while exploring a cavern on Alpha Onias III, Commander Riker was rendered unconscious by gases. While unconscious, neural scanners scanned Riker's brain. The scanners used elements of Riker's reality and constructed a holodeck simulation with those elements interspersed throughout, so that it felt real to him. What Riker wanted, the scanners made possible. For the remastered episode of "Future Imperfect", the original text of Riker's service record, which was not readable, was replaced. The name of this campaign was a reference to the Excalbians.
