For those who are curious, the background for the game is here: http://www.rumblepurrlion.com/stuff/dungeons_and_dragons/Zanxadar_player_background.pdf
Strangely enough, it allows for tieflings, but not dragonborn. Go fig! But it makes sense in context. And for the record, Zan-Xadar is pronounced "zank-SHODDer". ;P
Be warned, there may just be a giant enemy crab.
