Nearly all Greensingers are elves or half-elves, with a scattering of humans. They are habitués of Thelanis, if not natives of that plane, spending more time among the fey court than in the material world. Although some learn the sect’s ways on Eberron, most go to Thelanis and return as emissaries and defenders of the fey. Those with elf blood are most closely attuned to the wild freedom embodied by the sect, but anyone who chafes at the strictures imposed by civilization, or even the limitations of another druid sect, is a candidate for the Greensingers.
Unlike the other Eldeen sects, most members of the Greensingers are druids, with rangers making up virtually all the rest. The sect contains a smattering of spirit shamans as well. “Lay” membership does not exist: Greensingers are magical beings who are all spellcasters of some sort (or at least hold the potential). Quite a few have some levels in an arcane spellcasting class, usually sorcerer.
Greensingers dwell only within the Twilight Demesne and Thelanis, although they might travel to other realms. When they send an ambassador to Eberron, the meeting occurs within the Towering Wood. Communication with far-off nations is through magical means (facilitated by Gatekeepers and the Siberys observatories) or messages carried by emissaries of those lands. It is possible the Greensingers would emerge into the world if a sufficiently great threat demanded it, but so far nothing has met that criterion (whatever it might be).
There is no official costume for the Greensingers; that would be anathema to their fierce individualism and wild nature. They present themselves as the spirit takes them, and might change their appearance many times, even in quick succession. Some adopt outlandish garb of bright colors and unusual materials; some are clad in leaves; some wear the richest robes and drape themselves with jewelry; some are as naked as the twilight sky of Thelanis. They do not care if they shock the sensibilities of “mundanes,” for only the great dance matters.
What motivates the Greensingers as a group, let alone each member, is a mystery to all who are not part of the sect. Indeed, the sheer chaos of the faction is inimical to establishing an overriding philosophy. The Greensingers do have one shared ideal, however, which they reveal only to those who are fit to enter their rarefied circle.
The great purpose of the Greensingers is this: All the planes of existence are part of nature, and all should be made manifest. Unlike every other druid sect, they have no horror of outsiders, considering them to be as natural as earthly creatures. If a thing exists, they say, it was meant to exist. Even such universally reviled monstrosities as daelkyr and undead creatures are obviously intended to be. And existence itself is the highest authority to the Greensingers.
They also seek more connections between Thelanis and all the other planes, not just Eberron. They are most active when another plane becomes coterminous with Eberron, trying to anchor a portion of its essence to the material world even after its orbit takes it away. They also study the movements of the outer planes with respect to one another, and the effects of their being coterminous with and distant from other planes. Few are more expert on planar matters than the Greensingers.
