The author's name is Cassandra Vablatsky. My card has part of the A and Y at the end of her first and last names.
I heard somewhere that Cassandra is from the Greek.
I looked it up.
Possibly means "shining upon man", derived from Greek kekasmai "to shine" and aner "man" (genitive andros). In Greek myth Cassandra was a Trojan princess, the daughter of Priam and Hecuba. She was given the gift of prophecy by Apollo, but when she spurned his advances he cursed her so nobody would believe her prophecies.
Appropriate for a Seer, I guess.
