I saw books in a Dragonlance Product List that weren published with the Dragonlance setting. Whats up with that?
TSR has published a number of campaign settings, Dragonlance among them. Over the years, TSR started to think of the campaign settings as connected – a character from Dragonlance could somehow travel to another campaign setting. A whole multiverse was constructed, in which there were different levels of planes of existence, including heaven and hell. Basically, on one plane of existence was Dragonlance, and on another plane was a different campaign setting. Someone could travel to that other campaign setting through magic. In different books, the connections between the different campaign settings were explored, and some characters even traveled back and forth between the settings. The books and products where Dragonlance characters have gone to other campaign settings, such as in Lord Soth, or where the connections to the Dragonlance plane is explored, such as in Planescape, are included in the product list. The connection of Dragonlance to these other settings is highly controversial
