[RPG] Can characters travel between permanent teleportation circles?

dnd-5eteleportationworld-building

The Teleportation Circle spell (PHB pg. 282) states that in order for the spellcaster to "target" a remote teleportation circle he or she must know that remote circle's unique sigil sequence. What if a player or party wants to use a permanent teleportation circle to teleport to another permanent circle? This use case is not covered – or am I missing it?

I am including permanent teleportation circles in my campaign as sort of a municipal service "if you can afford or justify it" to get from one city to the next (and it won't always be safe, no). I have some ideas about how to set it up (as in how to have a "local spellcaster" set a destination for the portal) but I am curious if there is a method already defined elsewhere.

You aren't limited by existing mechanics when worldbuilding. As a DM, you are free to set your teleportation network as would be better for the story.

The Teleportation Circle spell itself suggests a wizard can learn additional sigil sequences during adventures when she meets the corresponding circles:

Many major temples, guilds, and other important places have permanent teleportation circles inscribed somewhere within their confines. Each such circle includes a unique sigil sequence—a string of magical runes arranged in a particular pattern. When you first gain the ability to cast this spell, you learn the sigil sequences for two destinations on the Material Plane, determined by the GM. You can learn additional sigil sequences during your adventures.

So if players want to use a permanent teleportation circle to teleport to another permanent circle they should probably be able to do that, providing they know the sigil sequence.
