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 a starship called the 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.
