Things to know beforehand.

• The water source located in The Void is salt water.
  
• You can access all shops from inside the void simply by talking to the shopkeeps through the walls.
  
• You MUST have your camp to level 1 to be able to create a flag. Visit the frog if you're interested in leveling up your camp.

Step 1

Once you spawn into a lobby (solo or public), enter the shop to the right of the bulletin board.

Step 2

Once in the shop, stand ROUGHLY where the red dot is in the image below. In the top right of the screen is a tent icon (hotkey "V"). Press the icon and place your "Island Entrace". This will spawn a flag that you will be able to travel to. If you cannot interact with the flag, it is too far away from the wall and you will have to move further away from the wall and try placing the island again.

Step 3

Finally, Interact with the flag placed in the last step. Doing so will bring you to your own personal island (pictured below). On the other side of the island is another flag. Interact with it and you will be brought outside of bounds of the shop. Walk away from the flag and you will eventually fall into the water. After respawning, you will be on the edge of the water and can fish to your hearts content, thus, pleasing The Void.

That's all there is to it!

Now, I will be honest in saying, I am not the first person to discover this, but I have taken on the role of Void Keeper. Please do your best to keep The Void a safe and welcoming place for all. Followers of The Void or not, everyone should be loved.

This flag "exploit" might be able to be used elsewhere but that is none of my business. Just have fun trying it, if you want!
