From YKTTW Working Title: Portal Guardian Series
Khym Chanur: Feline Wizards example cut, since the main characters are the maintenance team for the portal, not guardians waiting for things to come through.
- The Book of Night With Moon by Diane Duane is about feline wizards whose job it is to guard an inter-dimensional gate that lies in the subway underneath Manhattan.
Micah: From the YKTTW, some things that I don't know first-hand:
- Eureka is an interesting version of this - Sheriff Carter and the rest of the town regularly save the world by containing whatever horrific creature(s), space-time disturbance, Cold War era weapon system, berserk robot, or other miscellaneous mishap pops up in every episode. Never mind that the problem is almost always caused by one of said townspeople.
- Code Lyoko, if you're willing to stretch the definition of "portal."
- In The Dresden Files, the City of Chicago is apparently appropriately associated with Ley-Lines.
I also am not at all sure I got the Stargate series right, though I had more to work with there.
Gattsuru: A few of the villains of The Dresden Files are probably related to the ley lines; we're told much of the reason so many creatures of the Nevernever are around is because Chicago is a crossroads, and the necromancers of Dead Beat needed the energy for the big spell at the end, even if they may not have been aware of that at the start... but many others come for far more mundane or unconnected reasons — usually because they need a local human target, or the machinations of the Denarians, the vampire courts, or the evil wizards. This might be a good example, if you specify the more fae threats, though.
