This data pack adds a new item called the Ender Link that allows you to link it to a specific location and then be able to teleport there at any time. Be sure to download and enable the required resource pack as well!
The item is crafted with six gold ingots and one ender pearl as shown in the screenshots.
Once you have one, right-click with it anywhere in the world. It will gain an enchantment glint, and you'll be able to use it to teleport back there by right-clicking with it again.
I'm well aware that the item isn't particularly well-balanced, but I initially only made it because a friend requested it as a quality-of-life feature so I don't want to make it any harder to acquire one.
