Maybe something like this.
Rat of the Veil:
Everyone needs some place to live, and unfortunately sometimes that’s a dangerous place. So for the ratfolk of Cheliax who make their homes in hearts of cities where they are considered to be vermin or monsters, security is paramount. Ratfolk always survive by being smarter than their persecutors and form them the key to security is information. Much can be learned by skulking about at night, listening from beneath floorboards and in shadowed alleyways, but that sort of reconnaissance has it’s limits. So it falls to the ratfolk’s exceedingly clever arcane casters to learn more. The bravest wizards in the ratfolk community dare to walk openly in the daylight, using their arcane and mundane skills of disguise to go unnoticed and unremarked upon. In this way these arcane sentinels can gather street level information far more efficiently than a diviner or stealthy stalker. It is the Veil-Rats who have their fingers on the pulse of the communities in which they live, always on the alert for impending events that could impact the ratfolk communities. Always listening for the word ‘rat’ in a place and time that it might be better if nobody even knew ratfolk existed at all. For the Veil-Rats it is a hard lonely and dangerous life, any interaction with the people they observe risks exposing not only them, but the presence of their kin in the city. Now in Kintargo these measures have failed, and their extermination is a matter of policy. The ratfolk leaders, terrified of being eradicated at last intend to go into deep hiding and ride out the current vogue of hatred towards them. But it’s not clear if they can remain concealed against their hunters indefinitely, and the ratfolk communities cannot survive on lockdown forever. As a tide of dissatisfaction rises in Kintargo one of the young Veil-Rats wonders if it is time to reach out and throw his lot in with the other oppressed peoples who suffer under Thrune.
