Interesting premise.... teenagers ARE the pits.... but they usually don't manage to add a hunk of Hell itself to the "normie" plane.... Cover draft's a bit busy and "lurid" colorwise for my taste but also interesting!
Loving fantasy since 1960 or so, FRPGs since 1975 (appx), and CRPGs since 1985....
When the Dark comes rising, six shall turn it back,
Three from the Circle, three from the track;
Wood, bronze, iron; water, fire, stone:
Five will return, and one go on alone.
