Which is clearly what AJ Hawker meant by "under a separate license." They're under Titan's license with CBS rather than Pocket's. There's no such thing as "the license." There's Pocket's license (currently in renegotiation), Titan's license, IDW's license, Modiphius's license, Hallmark's license, etc.
About that.... I'm confused... The Prometheus novels were originally written in German, and published by Cross Cult, who is licensed to publish translated Pocket Books Treklit. But, Titan publishes the English translations. However, I understood that Prometheus does tie in with the established 'TrekLit' universe. Does this mean that Titan could also use other events from those novels in their licensed work somehow?
