As of Vice, Green Lucifer used his Seattle success to move up and run the entire West Coast operations of the Ancients go-gang. His long time (as of Elven Fire, set in early 2053) co-leader Sting, was left in charge of the Metroplex Ancients. The two of them had notoriously butted heads and had differences of opinion -- often regarding how independent versus Tir-connected the Seattle chapter should be -- for the better part of two decades. Some of the Ancients feel that without Lucifer there to prod and irritate and motivate her, Sting is just going through the motions once she's (finally) made sole leader of the city's gang.
As of Ancient Pawns, a 2011 CMP adventure, there is a disruption in that new status quo. Green Lucifer's Seattle-born son, Belial, a charismatic young elf who in many ways unites those Seattle and Tir-affiliated cliques within the gang, thinks that Sting is a little too ancient to be leading the Ancients. The influx of Tir refugees has swollen their ranks, there's a lot of other young blood in the gang, and he doesn't want them to stagnate because Sting -- who has been leading the gang for decades in-universe and for multiple editions out-of-character -- is too set in her ways.
The adventure itself deals with his challenge to her authority, with the player characters in the middle of the selection process.
As of right now, prior to that adventure being mass-published and made available, Sting is still the leader of the Seattle Ancients. Once Ancient Pawns hits shelves...things can change.
