This book has been a year long labor of love (and sweat, and dealings with eldritch horrors the likes of which the world has not seen on this Earth), and it's been a delight seeing it come together. Hektula's Khyber Codex is bursting at the seams with information on Eberron's infamous Dragon Below, going in depth to the monsters, civilizations, and inhabitants of the many demiplanes of Khyber. With environmental and encounter information, brand new statblocks, several new magic items, and plenty of commentary from the Librarian of Ashtakala herself, this supplement is a must have for anyone wanting to run sessions in Khyber.
