The Aberration Hunter's Handbook

Publisher's blurb: Alien horrors amass just beyond the veil of this world, turning their bizarre gaze toward the minds and bodies and natural beauty, hungry. Corruption. Madness. Mutation. Debased cults and squamous star-spawn. Elder Evils, ancient aboleths, beholders from beyond the moon. We need heroes to protect us. This document covers six groups of aberration-hunters, including character options and DM options for them.
