Lojal
Lojal was a Vulcan ambassador to the United Federation of Planets during the late 24th century. 

In 2369, Lojal, along with fellow ambassadors Taxco, Vadosia, and Lwaxana Troi, visited Deep Space 9 on a fact-finding mission to the Bajoran wormhole. Lojal was particularly interested in touring the space station, and expressed reservations about the competence of Chief of Operations Miles O'Brien due to the lack of functional backup systems. 

Later during the visit, Lojal commented on the calmness and logic that Doctor Julian Bashir displayed when a fire broke out on board the station. ()
