Every reference to Ed Greenwood's spell Nulathoe's ninemen makes sure to note that "ninemen" is pronounced "nin-em-en" rather than "nine men," making it a unique word of some sort.
I'm just curious whether this is some archaic word I've never run into, or whether any canonical source (even just Ed Greenwood's say-so) defines this term. Is there any dictionary or official source that explains the meaning of "ninemen" in this context?
