A DC 15 Religion check identifies the stone as the symbol of [[Sharess]], the Temptress.
The following information can be gained with a Streetwise check (Harrowdale locals may know Dayan from his childhood years, and in that case Dayan knows them too - see also Kira Nenthyn for more generic info on the twins):
DC 15: [[Kira Nenthyn]] and her twin brother Dayan are the adopted children of Breeandra Nenthyn, the former owner of the Fall of Stars. Breeandra passed away twenty years ago and left the club to the twins. The twins belong to the richest family of New Velar, and have a seat at the Seven Burghers counsel.
DC 17: Dayan is a bit of a playboy. He is a big spender bad with money, though he does throw great parties. He has a rivalry with Kira. The two often argue about the course to take for the club.
DC 20: The twins were born in the strife around the Moonsea. Their father was killed, and their mother, a friend of Breeandra, died after fleeing to Harrowdale.
DC 21: Dayan hangs out with a bunch of friends, who, while well meaning, have a penchant for getting into trouble.
DC 23: If he would set his mind to it, he would make a great politician or merchant, as he has excellent contacts and interpersonal skills. Unfortunately he is not very motivated.
DC 25: Dayan is a follower of Sharess. He also pays homage to [[Tymora]], [[Llira]], and [[Sune]]. He has aspirations to become a priest, though few people think he has the focus for it.
