Geb Slow to display emotion but appreciative of humor of all varieties , Geb ( pronounced " gheb " ) is the eldest member of the Mulhorandi pantheon . Also known as Gebthant in Thay and Gebakotep in Unther , he is a cautious and even tempered deity . History . Geb was the first child of the deities Shu and Tefnut . He wed his sister , Nut , and they had four children . The two were forcibly separated when Geb was ordered to join the Mulhorandi pantheon on Toril . During the First Empire , Geb was considered an Intermediate deity and his church flourished . However , due in part to inaction on the part of his clergy , Geb receives little respect today . Geb led his most faithful followers in building the Golden Forge during the Time of Troubles . This temple serves to prevent the eruption of a volcano that would devastate much of the Unther ' s coastal regions . Relationships . Geb is the father of Isis , Set , Osiris , and Nephthys . Other than in the case of Set , he remains on good terms with all his children . He also counts Flandal Steelskin , Grumbar , and Moradin as friends . Avatar . Usually appearing as a Mulan human of regal stature , Geb typically wears a earth - colored robe known as a kalasiris as well as golden bracers and crown . Red eyes glow faintly from the brown skin of his face , which often sports a beard cut short and braided . He typically keeps a quarterstaff close at hand . Powers and abilities . Geb ' s staff allows him to duplicate the effects of any earth - related spell or magical item . He is also able to negate all such effects . He can summon earth elementals to his side , and can exert control over certain denizens of the Elemental Plane of Earth . Other manifestations . Geb ' s will is often communicated through the acts of earth creatures such as stone golems and rust monsters , or those of animals such as bears and badgers . Church of Geb . The position of priest in the church of Geb is hereditary ; members belong to the House of Gebthant , and can claim at least one divine incarnation of Geb among their ancestors . Geb ' s clergy is largely composed of humans native to Mulhorand , but both dwarves and gnomes will occasionally follow the teachings of the King of the Riches Under the Earth . Temples dedicated to Geb utilize natural geographic formations in their construction as much as possible . Most of these sites are built underground to better facilitate this decision . At least one temple exists in each mountain range within the range of influence of the nation of Mulhorand . Worshipers . Followers of Geb spend much of their time working within the earth , seeking to discover the treasures that lie beneath its surface , or working the materials that are found in stone . Clerics must locate at least one new deposit of precious stones or vein of ore annually . Divine spell casters dedicated to Geb pray for spells at midnight . Clerics of Geb typically paint a series of three blue circles on their shaved heads that serve as a symbol of their calling . They often color their skin to a brown tint , and it is not uncommon for a member of the clergy to grow a short beard which is then braided . Usual vestments include a kalasiris , bracers , and iron - shod boots . These items are usually inlaid with small precious stones , and are often worn under a blacksmith ' s apron . Members of Geb ' s clergy favor heavy armor when preparing for a journey , and dress as the occasion dictates . Affiliated orders . The church of Geb supports no known combat - oriented organizations .
