Par-Salian mentioned Dalamar in Soulforge. Something about if Raistlin died or didn't work out or something, he would find someone else, and that Ladonna had mentioned a promising young elf named Dalamar. Is that what you're talking about? Because if you're saying that something about Dalamar being the dark-elf in the Test was mentioned in the Weis/Hickman books, I don't remember anything like that; and even though I haven't read the books in years, I have read all of them several times over.
