Carissa Sevar's Hell-worshipping sect seems to be illegal in Kelesh, just like the actual Church of Asmodeus, for some odd reason.
Highly illegal.
This particular squad of city guards was not much of a match for Carissa Sevar let alone Ri-Dul, and they could definitely disguise themselves if they wanted and continue, but there's a question of how to actually locate her worshippers in Kelesh.
