From publisher blurb:
The inevitables are at least as strange as the slaad. Monster Chronicles: the Inevitable takes the tick-tock guardians of order and shows you how to deploy them in an OGL or Pathfinder game. With insight into what makes the inevitable work (and not work), this Monster Chronicles installment is both celestial and totally practical.
The Monster Chronicles series provides ecologies and variants for lesser-known monsters as well as gaming classics. Every monster includes adventure hooks and surprises to catch even the most seasoned adventurer off-guard.
