The Bennu bird is an ancient Egyptian symbol of rebirth, also linked with the sun & creation. It may have been the inspiration for the phoenix in Greek mythology (wikipedia).
At Mythos in Second Life we have a remarkable temple house dedicated to Bennu! The Bennu Temple House is underground; it is spatious with an indoor swimming pool. with two entrances.
The entrance on the header picture can be reached by a steep, rocky path down from the Sol Invictus Temple. The other (and main) entrance can be reached by walking from the docks around the hill.
Visit Mythos in Second Life and find out what it has to offer.
