The oldest of the religions in Alsine, the worship of Kossuth, Dispater and the Raven Queen predate even elven civilization. Churches and shrines to these deities are ubiquitous - every city has a temple dedicated to each, and even small, frontier settlements feature a shrine dedicated to ‘The Three.’
The clergy of these faiths look upon the worship of ‘lesser’ deities as barbaric at best and heretical at worst.
