FOLIO: BLACK LABEL #9 [PRINT EDITION]

You've managed to breach the final level of the cult, but now a strange labyrinth of caverns stretches out into the darkness.  What horrors have the cult unwittingly unleashed in those depths is almost beyond reckoning, and yet you feel you must go on and discover anything left from the dark summoning, otherwise all might be lost. 

This is the final installment of the Arcania series, and concludes the events within.  This adventure is designed in both AD&D and 5th Edition mechanics, and if for 5-7 characters, levels 4-6.
