That used to be the incantation in a game called UO that allowed you to teleport in the world. What was cool about this though, is that people would be able to create books with specific locations on them and sell them to other players. Several popular books were popular grind locations, others were just cool areas in the game that you could get to. You could set it literally anywhere, meaning you could create your favorite guildstore book and within a matter of minutes teleport (through the use of a regeant) to all of them in a matter of minutes. You could create a book for your top 10 crafted sets. A book for those really hard to find NPC's that you seem to be running over or under but can't seem to find the ramp you actually need. A book for all of your friends houses.

How would this be implemented? Probably through enchanting. The regeants could be expensive, or somewhat harder to find (like double or triple heartwoods drop rate) and the mats to actually create a rune would be expensive. So one book could cost idk, ballparking 100k to make. What this would do is ensure that the populated areas remained popular and the streets are still full of people, provide a fun new side hussle for the explorers and crafters, and provide a unique opportunity for people to discover parts of the world they may have missed while running on a quest. Like a beautiful coastal sunset.

In order to prevent people from scamming people, (here's a book with 10 runes to the best grind spots, but really it's 10 runes to Davon's Watch) the description of the book if hovered over would provide the names of the places the runes were created at. Then, when you opened and read the books, it'd actually give more detailed information, like coordinates and stuff like that.
