Malurian

Malurians were an Alpha Quadrant race that was first encountered by the the Enterprise (NX-01) in 2151.

Physiology
Malurians were reptilian humanoids with a grey, scaly skin that covered their bodies. Females were much larger than males and stayed on Maluria, with each female taking a number of male Malurians as mates. Most males were also content to remain on the homeworld near their mates, however some were inclined to leave and explore the galaxy. Malurian males had no sexual interests in mammals, and mated for life with a single female. 

History
Malurian males operated in groups called alignments. Garos was part of the Radul Alignment, one of the few groups willing to leave Maluria and venture beyond their home system.

Reaching a technologically advanced stage by the mid 22nd century, the Malurians became masters of disguise. Masks designed by Malurian maskwrights enabled Malurians to disguise themselves as a wide variety of species. The more sophisticated masks allowed Malurians to operate in hostile conditions such as those found on Axanar. 

When first encountered by the Enterprise a band of Malurians led by Dular Garos had disguised themselves as Akaali in order to mine veridium deposits from their world. Due to the chemicals used nearby Akaali became seriously ill. Jonathan Archer and the crew of the Enterprise drove Duras and his Malurian counterparts off world, warning them to never return. Archer advised the Vulcan High Command to keep an eye on Akaali in case the Malurians returned. 

The Malurians next surfaced following the Earth-Romulan War, when Malurian pirates such as Garos feared the introduction of law and order would greatly hamper their activities.

By the mid 23rd century the Federation and Malurians were on good terms, with a Federation science team allowed to take up residence in the Malurian system to study Malurian society. Unfortunately, in 2267 the Malurian civilization was wiped out by the renegade Earth probe Nomad.
