Our Cancer sign is Laurana. Laurana is certainly emotionally dependent upon her cousin and foster brother, Tanis. (But you never realize *that* as she insists on being madly in love with him as she chases him from one adventure to the next.) She's also very possessive of him (not that anyone wouldn't be with Kitiara as an ex-flame), but does seem very into her emotions and is able to express her feelings about Tanis to just about anyone.
LaDonna is one of our scorpios. As the head of the black robes, she projects an intense, passionate (especially with Par-Salian) and mysterious persona. As a minor character, we know no more than that.
Raistlin manages (duh) to be one of the most intense characters ever. (Go Raist!) His passionate, obsessive, nature leads him to confront gods. (Does that scare the rest of you even a little?) No one ever knows what he's thinking (not that we're not glad at times), and his bouts with depression are legendary. (Poor Caramon.) As a typical water sign, Raistlin is moody, especially, as is prototypical of scorpios, in a dark, depressing way. (Again, poor Caramon.) His abilities with emotional manipulation (another talent that many Scorpios possess) is awe inspiring, as he manages to control Caramon, Crysania, Dalamar, and scare everyone else. His eccentric tastes and interest in the mystical are also scorpio-like, as is his rebellious nature.
Goldmoon, being the one who brought back the true gods and all, has got to be a tad bit spiritual. Based on her lack of strong emotional interests in anything, we're guessing that she's emotionally in tune. As the priestess of a healing goddess, she's also a healing helping sort, and, as the founder of the mystics, she's got to be one. She's a model Pieces.
Riverwind has no personality. Therefore, he belongs with his wife. And we suppose that a complete lack of emotional interests probably indicates some sort of emotional stability, oneness with oneself, and such.
