They had close ties to their neighbors, the Norcadians, and were also big fans of the Norcadian game Tsunkatse, at which they excelled due to their superior physical strength. According to Tom Paris and Harry Kim, Pendari were well known for their bad temper, as Pendari Tsunkatse fighters occasionally threw their opponents into the stands.
In 2376, while the USS Voyager visited Norcadia Prime, Captain Janeway and several others went on an away mission to the Pendari system.
