Teleportation Circles
A teleportation is a magical circle on the ground, created by an arcane spell. Each circle is ringed with a pattern of magical sigils that function like an address, allowing a caster who creates a teleportation circle to create a portal to any other circle whose sigil sequence the caster knows. Normally, a teleportation circle only remains for seconds after the spell is cast. Placing such a portal permanently requires the significant undertaking of casting the spell in the same location every day for a year.
The city of Brightridge has an anti-magic field to prevent teleportation into the city. However, teleportation to a permanent circle within the field bypasses this barrier. Legally, only one such permanent circle is allowed to exist in the city. However, there is an unauthorized teleportation circle in a secret chamber in the sewers, created by the Zonthosh Guild.
Teleportation circles are distinct from Arcane Gates, which are point-to-point links between fixed locations.

As you cast the spell, you draw a 10-foot-diameter circle on the ground inscribed with sigils that link your location to a permanent teleportation circle of your choice whose sigil sequence you know and that is on the same plane of existence as you. A shimmering portal opens within the circle you drew and remains open until the end of your next turn. Any creature that enters the portal instantly appears within 5 feet of the destination circle or in the nearest unoccupied space if that space is occupied.
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. You can commit a new sigil sequence to memory after studying it for 1 minute.
You can create a permanent teleportation circle by casting this spell in the same location every day for one year. You need not use the circle to teleport when you cast the spell in this way.
