Aldebaran

The Aldebarans sometimes referred to as Aldebaranians, were a species hailing from the technological planet Durid. They required masks to protect them when in oxygen-rich atmospheres. They were also known for the unique Force-using traditions of the Teras Kha Sages.

Biology and appearance
The Aldebarans were a tall race, typically of the same height and weight as Humans. Their skin ranged in color from brown to a crimson red. Most had dark, black eyes, although some were born with silver irises, a mark that was often seen as an affinity for the Stashik. Aldebarans were, as a whole, considered an unattractive species due to their strange facial structure. Their noses were described as falling short of becoming a beak, with a gaping opening that descended to the mouth, a toothless chasm with drooping fleshy strands. In place of teeth, Aldebaran had an upper and lower hard-palate, visible only when they pulled their lips back.

Due to Durid having a unique atmosphere composed of helium and a gas unique to their world called Iradium, the Aldebarans were forced to wear breath masks and protective goggles whenever in atmospheres of a different composition. This equipment protected them from carbon dioxide, nitrogen, and oxygen, which were fatal to a Aldebaran. The breathing mask also helped to amplify the Aldebaran's voice, as they were forced to shout to produce any sound when out of their native atmosphere. Without their protective goggles, Aldebarans were considered effectively blind when away from Durid. They were also able to survive in the vacuum of space for a short time though it was unknown exactly how long they could withstand it.

The Aldebarans also had heightened reflexes, a result of the extrasensory organs in their heads. As a species, they were thought to be typically quick and wise, but of a weaker constitution, when compared to other species. Aldebarans were also said to communicate with their minds using a form of telepathy. This form of telepathy was thought to be a Stashik technique known only among the masters of the Teras Kha order, but was later exposed to be a lie spread by the Teras Kha sages.
