From the introduction:
The original The Accursed Tower adventure module was released by TSR in 1999, right at the last gasp of 2nd Edition D&D. Written by R.A. Salvatore & The Seven Swords (Salvatore’s gaming group), the adventure features cameo appearances by two of Salvatore’s famous characters from his novels, Regis the Halfling and the dark elf Drizzt Do’Urden. The adventure is split into three sections: a largely uneventful caravan journey from Luskan to Icewind Dale; researching the background information and location of the main dungeon; and the eponymous dungeon itself – a sunken tower occupied by a host of cursed undead and a dangerous array of traps.
