Ahh yes whatever DID happen to Veridian, Alya, and the mask of Races. And what WAS the deal with their family.
Well when Veridian died, his soul belinged to the Spider Queen. She tortured him for a couple of lifetimes outside of time and then traded him over to the Queen of the Unseelie court to train her hunting parties on. Veridian was actually True Ressed by Alya who, growing tired of Richter's promises to pay her back, decided to take the matter up with the church of Kelamvor directly. It was a sweet sweet irony to her to use the money from someone who worships a god that doesn't believe in bringing back the dead, to pay for her brother's ressurrection, especially when it was one of the two people who denied her all of her brother's possessions in the first place. Especially when Veridian Died trying to save Richter's life. It also didn't help that Richter was nobility and Veridian and Alya were street urchins who had to grow up begging at the feet of people like him. So when her brother came back, Veridian feared the Unseelie Court would send people after him, so Alya gave Veridian the mask to hide himself, since she had magic that could do the same.
As for Veridian And Bernadette, after Veridian was cursed with the Fang Scarab, his first action was to seek help from the temple of Corellian, who, when they saw what he was, ran him out of town, and forced Alya to disown him on pain of death. When the first person he meets is a human wannabe cleric of the god who's church shunned him, he didn't exactly go out of his way to endear himself to her. The only person he trusted in the party was Timmay, but after he died, and everyone had no problem treating him so roughly, he had no problem leaving them all to the spiders when the time came.
