The Worldroots are extensions of the Oak of Ages, found within the heart of Athel Loren. By the time of the Forgotten Season, they had spread across many lands, creating a web that the spirits of the wood could traverse to reach faraway places. So did the great forest first discover the summerlands of Avelorn, and encounter the Elves of Ulthuan, long ago.[1a]
Since that time, the worldroots have been utilized by the Wood Elves to travel as the spirits do, the first time being when Avelorn was besieged by the Daemons of Chaos, Durthu allowing the Everqueen Astarielle's wounded children to escape via the ancient pathway.[1b]
