ELFFAF

They come from constellation Bootes, near Asellus Primus.

They also resemble the "grays" but are not "related".

This race has 4 different genders and they are known to be benevolent.

The purpose of their visits is unknown, but they seem to have a special interest on raw materials/minerals (?) as they have been often sighted near old mines.

Last sighting: San Isidro de El General, Costa Rica, in 2005.
