MATRAX

Despite their appearance (installs fear in Humans when sighted) this race is not known to be agressive.

They can live up to 400 years.

They come from constellation Delphinus, near Sualocin.

They have been visiting Earth for at least 4.000 years, but were sighted quite often during the 19th century.

They served as inspiration for the alien race in the movie

"Independence Day". (note of Petro and me: this the other -second- mention about a race being used as inspiration for that same movie)

Last sighting happened near Marseille, France, in 1996.
