Fight or Flight is a new setting book for 5th Edition D&D that's up on Kickstarter now. It adapts the avian-based setting from the books, Avian Adventurers, Myths and Magic, and Idols of Aether, and lets you head down into that world of feathers, beaks, and talons. This setting is truly for the birds (but that's the point).
From the campaign:
Fight or Flight is an ongoing series of books based on the lives and history of individuals within Aerikar, there are currently three books: Avian Adventurers, Myths and Magic, and Idols of Aether. Writing these books required a lot of thought about their world and lore, which formed the perfect setting for a D&D adventure; an adventure which I have personally been running for the last few months.
Fight or Flight: Kingdom of Aerikar is a campaign setting designed for Dungeons & Dragons 5th Edition, and focuses on the avian, a race of bird-like humanoids and their busy and historical kingdom.
The campaign setting introduces multiple expansive regions full of towns and cities, along with quest prompts and variant descriptions. The setting also introduces new races, classes, backgrounds, magic items, and spells.
All of this is alongside all-new artwork in a hardcover book with over 100 pages of content!
The Kickstarter is up and running now and it's set to go for another 29 days.
