The worship of Mammon was made legal in
Westcrown in -322 some 37 years after a similar legal case involving the worship of
Asmodeus and as with the latter case the event went unnoticed by the general population of the city. The first chapel to Mammon was, however, built in the noble's district of Regicona in -314 hard on the heels of the consecration of a similar building dedicated
Asmodeus. Observers saw this as an effort to have a simlar level of influence among the city's ruling class.
In fact the two churches have taken a slightly different approach, as wags are fond of saying, with the Church of Asmodeus thinking
that corrupt political influence would lead to wealth while the Church of Mammon calculating that wealth would lead to corrupt political influence. Be that as it may the Church of Mammon is also clearly interested in followers who will sell their soul for money irrespective
of politics and was the first of the two rival churches to build a small but lavishly appointed temple on the mainland in -265.
Like its rival it has attracted a special following from the tiefling underclass and pays them generously. It also provides the tieflings
with a rich livery however humble their role in the church might be. The message to the other races of Westcrown is very much 'if the lowest class
in Westcrown can do this well in the Church think what riches await you'.
Although the tieflings working for the church are required to sell their souls just in order to obtain a desirable job the average member of the Church's
congregation experiences a much lengthier and more subtle seduction which typically lasts many years if not decades. This enables the
priesthood of the Church to pretend that selling your soul is just one option, albeit an extreme one, in the financial transactions that followers may have with the organisation. Although the Church has less influence than the Church of Asmodeus among the noble families and
Westcrown City Council it nevertheless has far greater influence amongst
wealthy merchants and bankers and puts great effort into fostering an image of 'respectability'.
