Creating a Permanent Teleportation Circle?

[S'mon]

I was wondering if there are any official rules for the creation of Permanent Teleportation Circles, needed for eg the PHB Linked Portal ritual? Do they have a level & creation cost?

Yep, "Create Teleportation Circle" ritual, Manual of the Planes, p. 149. Level 15, cost is 1000 gp per square, plus 5 healing surges. It lasts 24 hours, but it can be sustained by spending 1 healing surge per day. If it's sustained for a year + a day (harsh!), it becomes permanent.

Although, for a non-adventuring NPC it's not so bad. Say, the city commissions you to sustain the ritual for a year, and for that year the city pays you some nice cushy salary for not doing anything dangerous.

Its also worth noting that any character can participate in the create teleportation circle ritual, even if they are not the ritual caster, by donating healing surges. In our party my swordmage is currently two surges down per day (for our two in progress circles) as he has the most to spare. Being able to cross the continent rapidly is worth a great deal to us, and as our wizard has the quick portal power it provides a great escape option

Thanks! That's close to what I expected, and should work well in most of my campaign worlds.
