Winter Silence

Exploration Stage: Bridge
From: Detective
Description: Something really strange is happening in the world of the nature spirits. For example, do you hear any birdsong? Usually the hymns of awakening nature sound out from the magical tree, but now it's quiet. Suspiciously quiet. Try to find a bird. Maybe we'll find out what's wrong.
Completed: Wow! The lark you found is covered in frost and can't sing its melodious songs. The winter frost hit the birds hard - life is barely flowing through their venis. Who did this?
