SMP server mini-contest

Today, we launch a secret shop on the SMP server which will have various blocks and items not normally available in-game. The first player to find the shop will receive a reward of 1000 cubits.
Here's some hints:

• The shop is within 1500 block radius from spawn
• But not too close to spawn
• Majorly underground
• You'll know it when you find it
• Wherever I put it

There will be an unlocked chest inside of the shop. Grab the contents as proof that you were there first!
If you still don't have access to the SMP server, just send me a PM.

Good luck!

UPD: The contest is over. The winner is Emilgardis!
