Circle of Masters: reserved for those infected with Zuggtmoy's spores
Inner Circle: consists of the two sovereigns and a select few adult myconids they hold court with
Circle of Builders: builds things that the community would benefit from, such as irrigation systems
Circle of Explorers: serves as the temporary home for restless myconids that brave the Underdark as scouts, patrols, and pathfinders
Circle of Growers: farmers who ensure the soil beneath the pools remains fertile and tend the fungi there
Circle of Hunters: tracks down creatures that have died near the grove, bring their remains back, and allow them to rot and join the cavern's detritus bed
Circle of Sporers: devoted to sporing new myconids; babies are only a few inches tall and have no awareness, but quickly grow into myconid sprouts
