The Roylans are a diminutive humanoid civilization native to the planet Royla.
History
First contact between the Roylans and United Federation of Planets occurred in 2230, accomplished by the crew of the USS Kelvin
Biology
They have green bony skin and short eyestalks in black sockets, with scaly bodies and clawed digits. They have five fingers on each hand and four toes on each foot. The shape of the bony marks on their heads vary widely from individual to individual.
They also appear to have acidic mucus, and when they sneeze said mucus can dissolve metal.
Society & Culture
Not much is known about Roylan culture as the race is very insular and those that leave their planet behind do not seem to be very talkative about it.
