Hi,
I was interested to know the canonicity of an article in Dragon Magazine 114 (1986). It is written by Kevin Stein and Margaret Weis and copyrighted to FASA. It is a preview of TRO 3026 and contains almost word for word sections of text and official illustrations, however there are some sections of text that are slightly different to that which made it to the printed version. Given the authors and the copyright, is this source considered canon?
