Book of Lairs: Abandoned Places
For my fourth Book of Lairs (Abandoned Places) this collection of lairs consists of two-page spreads of maps and text¸ with monsters taken from the Adventurer¸ Conqueror¸ King System (ACKS) core book and the Lairs & Encounters book; but it is compatible with other old-school fantasy games with hardly any effort. This book is themed¸ with each lair being abandoned by its former occupants and taken as the lair of some other creature or creatures.
There are 13 lairs in all.
