Freemasonry in the Federation

Terran Freemasonry accepts all adult males of good character, including transmen, who reside in a Grand Lodge's jurisdiction. Prince Hall Freemasonry is available for those men who want it for cultural reasons, but the General Grand Lodge of Earth accepts all males without regard to species differences, as long as they are of good character and believe in a supreme being. The Shriners accept men from Blue Lodges as well as Prince Hall Lodges.

Eastern Star members join through relationship with a mason, by membership as minors in the Order of the Rainbow, or by independent request, as masons may do. The Sisterhood of Light is a sororal group founded in the early 2200s by adherents of Co-Masonry (for both men and women), who wanted an all-female order.

The primary work of the fraternal organizations on Starbase 109 is to support the Shriners' Pediatric Hospital on Deck 1000 and other charities as each organization desires.
