"I mean, this just doesn't happen. except... well, what about this? the tunnel goes right through the entire earth and spits me out the other side into the heavens, and somehow I just crash-landed on a totally different world?" His breath snagged. that felt worse. Much worse. now he wasn't even on the same world?
"but I don't want to go to the next world," Griffin said in alarm. "I want to go back to my own world."
Frieda nodded. "From what I understand of the tree, it is a kind of current, a slipstream that guides us where we most need to go. For the living, there would be a different path then for the dead."
Frieda chuckled. "it is huge. but, no, the tree is not the destination. the tree is a conduit, a passageway to the next word."
"they all go to this tree and live inside it?" Griffin asked. "it must be huge"
"its my fault. all of it. if i hadn't hurt luna, if i hadn't got dragged down here and made you come after me so that now-
"Griffen. it was an accident. you did the best you could, and you brought luna with you, and you made it to the tree, without my help."
