My gaming group had a big ole Planescape campaign in 1995/1996, and the DM, myself and my then-girlfriend, now wife, went to Gencon. We met the creators, and did some fun little Planescape sessions they had set up. In our campaign, my wife was playing a red-headed tiefling with a devil's tail named Lilah. Being nerds, we of course told the Planescape devs all about our campaign. My wife even has a sketch of Lilah from Tony D in the (then, just released) Planewalker's Handbook.<p>In 1997, Planescape Torment came out, and we loved it. However, it was a bit shocking to find they had an NPC named Annah, that was a red-headed tiefling with a devil's tail. We still think Annah was heavily drawn from Lilah!
