Sometimes in the forest dusk it seems that the branches of a tree far off have been lit by a lantern and begun to move. That is the ancient gnome making his rounds — the Night Warden.
A helmet of living branches and moss makes him nearly invisible when he stands still among the trees. The lantern burns low and steady — enough to see by, not enough to be seen from a distance. A warden's light, not a traveller's torch.
When the sun nearly touches the horizon, the Owl rises into the sky and circles the surroundings. Spotting something amiss, it flies back to tell the gnome. And then the Warden lights the candle in his lantern and sets out to help — without hurry, but without delay.
He keeps no record of his rounds, but he remembers every night something unusual occurred: the exact location, the season, the phase of the moon. No need to write anything down. The forest, he says, keeps its own record. He is simply the one who reads it.
The moss and lichen on his branches did not appear all at once — they grew gradually, year by year, the way they grow on old trees. He never tried to remove them. Why would he? The forest simply recognises its warden and marks him in its own way.
