The child is of course a Dhaot, but fortunately his bones lie in the road (he hid under the wagon when the "monster" attacked, but the Inix spooked, and he got crushed under the wagon wheels).
Dras knows his home is a farm outside Nibenay. Once there, his mother (a farm slave) insists that they all go demand that Dras be interred in the noble family's mausoleum. She tells the party that Dras' father is the noble in charge of the farming village and that he had Dras sold off when the boy's paternity started to become undeniable.
The nobleman vehemently denies being the boys' father, but relents when Dras' mother promises to the nobleman's wife (his wife is a shrill and proud woman - she may not love him, but she'll make his life hell if she discovers he had a bastard with a slave woman). The family mausoleum might be haunted, at the DM's option.
Before fading away to the Grey, Dras tells the party that his caravan's pay chest got dragged into the silt along with some of the guards. They'll just have to kill the "tentacles and teeth" monster if they want it...
