"You ask what does it mean… It's to relive the history of our Forest Elves' birth," Ebony replied. "After crossing the sea, our ancestors encountered Undead creatures on this land and the World Tree was overrun by them. The strongest warrior of our race, along with his priest wife, joined forces to defeat the corruption and save this land. So, to renew the contract, we need Lord Nehe to unleash his full potential in undead spells, eliminate as many undead creatures as possible, and purify the World Tree. Finally, we need to choose a new Father of the Wild and Listener, and kill him as in the myths, just as our ancestors did."
So this was what renewing the contract meant?
The other party's answer stunned William. Recreating the past to affect the present—it sounded like ritual magic.
No…
Ritual magic merely reproduced myths, and those myths were based on creation. Reproducing those myths could trigger corresponding phenomena.
