Fleet Captain Lennan was a Minbari of the Religious Caste.
In 2260 he lead a small fleet of Minbari Cruisers along with White Star 1 to defend Babylon 5 from the Earthforce ships attempting to cease control of the station. Later, when visiting the station he was captured by Nightwatch member Boggs, along with Delenn and Lennan's aid. Unfortunately Lennan's aid was executed in an effort to make sure the command staff took the kidnappers demands seriously. [1]
