Vivifying Air

Exploration Stage: Post Office
From: Mr. Black
Description: Normally, it's easy to send a capsule, but now the pneumatic tube that leads to the Security Service is blocked by the fog. It's fine though - our guys had air tanks to protect them from inhaling the fog. We have some around here, bring one.
Completed: It's believed that if you breathe the air from a tank, you can protect you memory from the fog. Let's clean out the pneumatic pipes with air, just in case.
