Captain Rupert Crandall was a male individual who lived in Infinity Lake on Nepenthe during the late 24th century. He claimed to have "been everywhere, from Qo'noS to Tyken's Rift," and owned the starship Inside Straight.
Kestra Troi-Riker was friends with Crandall, though her parents William T. Riker and Deanna Troi were less impressed with him. In 2399, Kestra suggested he could help Jean-Luc Picard and Soji Asha. She contacted Crandall with the details of Soji's homeworld, which he was able to identify as a planet in the Ghulion system. (PIC: "Nepenthe")
