The structure of the Green Dragon Society is extremely tight-knit, with the Green Dragon Society Leader at the head, followed by the Hall Masters of the Azure Dragon, White Tiger, Vermilion Bird, and Xuanwu. Beneath these four main halls, there are twelve subordinate divisions, respectively named from Yi Yue to Qi Yue, down to the twelfth month. Each division controls twenty-eight to thirty-one minor leaders called Incense Masters, and the number of underlings each Incense Master has generally depends on the regional needs.
