Deep freeze

Exploration Stage: Polar Quarter
From: Martha
Description: Why did the "Snow Queen" lock those poor hunters in town? Even Nicholas was trapped in that frozen land! And what did she do then? I can see her face, it's like a mask of ice. Look for something like that in Arctic Town.
Completed: Apparently, wearing this ice mask increases the power of the "Snow Queen". The rivers around the town have frozen over, down to the smallest waterways. Even the riverbeds are completely frozen over. People couldn't even get water or fish!
