Lloigor

The Lloigor are an alien race of interdimensional energy-based creatures that can assume reptilian forms and probably, the source of dragon legends.

Biology
The Lloigor are vortices of energy invisible to the human eye. However, they can take various forms, among which the reptilian appearance that they usually use to demonstrate before mortals stands out. They don't need to feed.

Behaviour
The Lloigor have a twisted mind filled with so much darkness and pessimism that anyone who came into mental contact with them would be driven to suicide. Other peculiarities of the mind of these beings is that they lack feelings and that they never forget, so their ideas are always objective and immutable.

Among the powers of the Lloigor is the ability to assume a corporeal form or move things with the mind.

History
The Lloigor came to Earth in a remote past led by their leader Ghatanothoa and settled on a lost continent, possibly Mu. There they built a prosperous civilization by employing slave labor, whom they mistreated with terrible torture. However, when Ghatanothoa was sealed off, the Lloigor began to weaken, so they retreated to inaccessible places.
