The Dallas/Fort Worth International Airport

The second busiest airport in the world, DFW receives thousands of flights a day. A major transportation hub in the U.S., it's a frequent destination and/or stopping point for traveling celestials.

Marc has his agents at the airport, and keeps tabs on anything that happens there. This is known to the infernals, so they particularly avoid making a disturbance in the airport, especially in the wake of 9/11 (Marc is rumored to have an entire flight of Malakim on emergency alert, ready to descend on DFW within seconds). Asmodeus also has a Servitor assigned to DFW, trying to record any sightings of individuals involved with the War.

DFW is the closest thing Dallas has to a "neutral ground." On the rare occasions when angels and demons want to talk, they will usually arrange to meet at the airport. Marc's agent expects to be informed of any such meetings, as does Asmodeus' (though this doesn't always happen). If they aren't informed, any untoward incidents that occur will bring severe repercussions on the guilty parties.
