Longbark is a female everwaking oak who was the oldest known tree in the Forest 
Primeval, possibly as old as Meri Greenwood himself. The evil sorcerer Razzorbauch feared her power, and so uprooted her and transplanted her in Bedd Chwiorydd Tair, or Tomb of the Three Sisters (Towmb of þe Three Susters), an extinct volcano with two craters in the southern Pitmaster’s Kettles, when he imprisoned the three Fairy sisters there at the time that he turned the forest into the Chokewoods in Good Sister, Bad 
Sister. The very Great Staff of Power was made from one of her branches as was the powerful stick given to Ocker the raven by Meri Greenwood. It is Longbark to whom the Fairies turn for advice on Abaddon in The Burgeoning and the Damned Baby in The Reaper Witch.
everwaking oak – Quercus claudo-ilex R., derwin hollol effro (Old Niarg Standard) (wide 
awake oak), a dioecious evergreen oak with holly-like elliptical 1″ x 2″ leaves with spiny toothed margins, glossy dark green above and whitish green below, which suddenly fold along the midrib and collapse at each end of the petiole when exposed to certain thigmatic and electromagnetic stimuli in a manner reminiscent of the mimosa’s response to touch. The narrowly oblong 1/4th” x 3/4th” acorns are enclosed by a shallow scaly cap, and are born singly on the end of a stalk. The trees are much the same stature as burr oaks, being thirty to fifty feet tall with a spreading crown somewhat broader than the tree is tall. They are indigenous to very restricted parts of the thinly forested, savanna-like rolling uplands of the Forest Primeval flanking the great Fairy Valley. A number of them, particularly the female known as 
Longbark, are claimed to possess a magical intelligence which the Fairies regard highly. A number of wizard’s staves and rods have been made from Longbark’s branches, including the Great Staff of Power. The Fairies make a slightly bitter tea from their leaves which is similar to yerba mate, except that its alkaloid concentration is four to five times as strong as that of mate and must be drunk with milk. The Fairies also make bread which can be kneaded from a glutinous flour made from their acorns.
