Rillifane Rallathil (RILL-ih-fane RALL-uh-thihl) is protector of the woodlands and guardian of the harmony of nature. He is often likened by his clerics to a giant ethereal oak tree, so huge that its roots mingle with the roots of every other plant on Wearth, that stands at the heart of Arvandor, the High Forest of Olympus. The great tree draws into itself all the ebb and flow of seasons and lives within the woodlands of the green elves. At the same time, it defends and sustains those lands against disease, predation, and assaults of all kinds.

Rillifane is quiet, reflective, and enduring over eons unchanged. He is the least flighty of all the Seldarine (elvish Powers), the least likely to act on a whim, and often grave and self-absorbed. The Leaflord rarely ,manifests himnself on the Prime, disliking direct action and preferring that his clerics carry out his wishes.

The Great Oak draws energy from all the living creatures of the world and nourishes, sustains, and protects them from outside threats. Live in harmony with the natural world, allowing each living being the opportunity to serve out its natural purpose in life. As the Leaflord's countless branches, his faithful are to serve as his mortal agents in the natural world- Defend the great forests from those who would ravage their riches, leaving only destruction in their path. Contest both the quick and the slow death of Rillifane's bounty and hold strong like the great oaks in the face of those who can see only their own immediate needs.

The church of the Leaflord generally keeps to itself, extending itself only to help fellow elves and other sylvan beings. The church hierarchy is organized regionally and divided into branches, as each type of cleric serves a specific role. The druids who compose the bulk of Rillifane's clergy tend to the health of the forests and those who dwell within, fiercely contesting any attempt to further reduce those forests that remain. Many clerics serve as ambassadors of the faith, working outside the communities of the elves to educate other races and even other elven subraces how to better dwell in harmony with nature.

Rillifane's priests are deadly enemies of those who hunt for sport or those who harm trees maliciously or unnecessarily. Rillifane's clerics are charged with rooting out and destroying sentient plants whose nature has been twisted by external forces into a warped perversion of nature. In particular, they seek to destroy hangman trees, obliviax, death's head trees, black willows, serpent vines, and any form of evil treant, including dark trees.
