Guardian Griffons of the Tower of the Dead

A full standalone adventure for 4-6 4th level griffon characters, including rules for creating griffon characters (Griffon ancestry rules, 3 new ancestry feats, and 4 Griffon heritages). The adventure should take 4 - 6 hours to play through, and includes a cinematic chase option as well as a range of undead critters to challenge your players. Also included are four unique magical items (5 if you include the cursed one), and 3 new spells.

This scenario is balanced for Pathfinder Second Edition, but could easily be retrofitted for Pathfinder First Edition or 3rd to 5th edition of That TTRPG We Can't Name Due To Trademark Laws - or any other system that allows for high fantasy combat, griffons and vampires.
