Ten years after the end of the War of Avalon, Britain's Mages are still licking their wounds. None of the Fellowships want a renewal of hostilities, and none want to give the Circle of Red another window of opportunity, but all sense a serious possibility of gaining an advantage over their weakened rivals. It's a precarious balance, and none too stable
The Night's Bridge Chantry is essentially a collaboration between the three strongest Fellowships of the British Isles - the Messianic Voices, the Old Faith, and the Order of Hermes. It's not a happy collaboration; Father Thierry, the leader of the Chantry's Messianics, is quietly and subtly incessant in his efforts to convert the other two Orders to a Christian point of view, something that neither appreciates. The Old Faith has an old grudge against the Order of Hermes for the destruction of House Diedne, and the Order of Hermes resents its recent humiliation at the hands of Clan Tremere and is touchy at any perceived slight to its vaunted power. Fortunately, the Mages have now had a few years to grow accustomed to each other, and a certain grudging affection is slowly and reluctantly starting to develop between them. It remains to be seen if this newfound bond is too fragile to survive serious adversity.
The fire of the Crusades has not yet burnt itself, and conflict between Christian and Muslim still burns hot in Spain. Even the supposedly more enlightened ranks of the Mages are rife with suspicion and hostility towards Islam and its adherents. The Subtle Ones have no declared presence in London, although it's possible that their agents are active in the city, most likely working against Legion and its allies.
The Messianics paid a heavy price for trying to guide the Church against their rival Mages during the War of Avalon. Their presence in the ranks of the clergy has been greatly thinned by the zeal of the Shadow Inquisition, and they have quietly adopted far humbler, lower-profile roles than they prefer in order to avoid attracting attention. Rather than seek to exert influence through mortal institutions, they have switched their focus to converting their fellow Mages. This has not increased their already low popularity amongst their fellow Willworkers.
Although it suffered heavy casualties during the War of Avalon, the Old Faith emerged from the conflict stronger by default, simply because both the Order of Hermes and the Messianic Voices, were weakened to an even greater extent. The exigencies of the conflict forced a measure of unity and organization on the Fellowship, but it remains highly individualistic and decentralized in comparison to its two main rivals.
Hubris is punished by Nemesis. As inheritors of the Greco-Roman tradition, that's something that the Order of Hermes should have understood very well, but it managed to take most of them by surprised. Humiliated by the losses they suffered in what they assumed would be an easy conflict with the renegade House Tremere, all too often bested by rival magical Fellowships, they proud Mages of the Hermetic Fellowship are in the midst of a painful process of reassessment. Torn between pride, and the recent memory of where overweening pride leads, the Hermetics retain their outward appearance of arrogance but not their formerly invincible self-confidence. It's a combustible mixture...
The Spirit Talkers have always been a solitary Fellowship, and the War of Avalon affected them perhaps less than any other native English Mages. A few of them distinguished themselves during the War, using the spiritual magics to combat Legion and its allies, but for the most part, they continue as they always have, isolated guides to inward-looking rural communities. There are none in London, although a few of them make their homes in the villages and hamlets around the city.
The days of the Vikings are long gone, and the glory days of the Valdaerman Fellowship are likewise behind it. There are no acknowledged followers of its practices in London, although the name of Eldgrim Liefsson, the ancient northern Master, is widely known - albeit as a distant and terrifying bogey-man rather than a person.
