VEGANS

Planet of Origin: Vega XXI (Although it is not known if the planet called Vega XXI by the alien is the same one humans call Vega or if this is an homonym)

Vegans are a sentient man sized humanoids drapped in a luminous aura who developed a pacific advanced civilisation. It is not known if they possess telepathic abilities but when an individual of the species die every specimen is aware of the event regardless of the distance they're at. Their sexual unit is composed of five individuals. They take part in an interstellar community of species sharing a network of portal linking their worlds together.
