Stellairian

Stellairians are a sapient spacefaring humanoid species.

Biology
Stellairians are a physically imposing species, taller than the average Human and strong enough to break a wooden table in half with a single punch. They have bifurcated noses, four-fingered hands and pointed ears. The ears are located on the neck.

Their native atmosphere is different from Earth's. Although they can survive in Earth's atmosphere, it causes them to age rapidly. Without treatment, a Stellairian exposed to Earth's environment can age the equivalent of a hundred years over the course of a single day.

Culture and society
They're a technologically powerful species which can destroy an entire planet and once incinerated the Frostifarians' planet with a solar flare.
