Thronur's Delving, Withering

[Egon the Monkey]

Is it intentional that you are safe from the withering immediately outside the Delving, but affected by it within?

[Howlando]

Yes :-( It's just on the edge of things... but not quite in the forest. If only dwarves liked to live in the trees!

However, the withering rate is very low there.
