Rather than a tree root, it might be more accurate to describe it as a 'wooden wall', except looking upwards, that part which should have connected to the main body had already broken off.
Laine felt some regret about this. The tree heart that supported the World Tree of the Nine Realms was an incredibly precious treasure. He had no idea whether the main body of Yggdrasil had fallen to a certain layer of the Realm or had directly collapsed into the true void with the Nine Realms, reverting from 'being' back to 'nothingness'.
"Where is Urd's Fountain, where is it?"
His gaze swept the ground, but unfortunately, Laine couldn't see anything that might suggest the presence of a 'Fountain', much less the sacred springwater that contains 'vitality' and 'purification'.
Fortunately, he was accompanied by a 'local'. Before becoming a head, Mimir must have come here.
