Blastula

The Blastula, a.k.a. Blastulans, are a spacefaring nomadic alien race.

Biology
Blastula are humanoids which prefer high temperature environments, although they're also capable of surviving in Earth's normal temperatures.

They have telepathic abilities that allow them to sense the presence of other beings and probe their minds easily. Only a very well-trained mind can hide information from a Blastula.

Culture and society
Their technology is very advanced. They have ships the size of Pluto and can cross the distance from the galactic edge to Earth in less than 24 hours. They can also create sun spots and even artificial suns.

The Blastula inhabit Earth-like planets until they consume the planet's resources and move their entire civilization, leaving another devastated world behind. They thrive in scorching environments and will raise the temperature of worlds they intend to conquer.
