Today, a group of heroes traveled through the roots of Yggdrasil and patched up its wounds. Nerthus' last words through the Rachel Pope were of gratefulness. She also indicated that while the tree will be safe for now, excess deaths will continue to harm it, and prayed for peace in Midgard and the other realms.
Odin and Freyja in Prontera also expressed their thanks, while still refusing to comment on the purpose of the Gods' Challenge. It seems that they are preparing us for something, but it will remain a mystery... At least, for now.
