Legacy of a mis-spent childhood, adolescence and young adulthood. (In another 10 years, I guess I'll have to add adulthood to that list...)
I've got a pretty good memory for these sorts of details, as the evolution of game design fascinates me. OTOH, I know very little about most of the settings of the 2e era, especially Planescape.
Ballarat is 30 km away; I'm about 140 km from Melbourne.
Find Melbourne on a map of Australia (it's in the south-east), and then go 140 km northwest. I'm still in the state of Victoria.
I live on a mountain (Mt Bolton) in a bluestone house surrounded by forest.
There's some pictures of my home here:
