If you take a left turn off the subway platform, you’ll find a secret door. The door will open for a gift of silver. Once through, you’ll find that you’re outside in a magenta twilight, with lush, fragrant flowers and strange, beautiful animals. Leave them be.
Follow the path until you reach the sign, pointing you to summer and winter in opposite directions. Behind the sign, you’ll see a lake. Swim to the island at the center of the lake.
At the center of the island, there is a well. Drink from this well and call me in the morning.
