No. Yggdrasil has not been cured, however we have made advancements.

On the 4th of Lleian, followers of Lleis, Haern and Slyphe and many
others gathered at the base of the world tree to attempt to cure it. The
idea was, with each parts of the Triad represented, we could call the
tree from the corruption.

The followers of Lleis begun by singing hymns. Lady Slyphe's dragon
showered the tree with her sea water, and the followers of Haern began
placing the corpses of animals - the blood of Haern - at the base of the
tree.

The tree shuddered, groaned, creeked, and did whatever else a tree can
do. Now, instead of just a foul odor, it is mixed with the scent of rain
and leaves. At the roots of Yggdrasil, a melody of hope counteracts the
mournful song, and the same scent of rain and leaves acts alongside the
foul odor.

Our attempts have not cured the tree, but they have made a small
improvement.

We continue looking for a cure,
