In unfamiliar lands, peril can hide in peculiar places — so in Shadow & Twilight it would be wise to keep your wits about you!

This examination of the Shadowfell and Feywild will throw you into the thick of it with options for DMs that include a plethora of captivating and creepy creatures, shifty NPCs, and unique locations.

As a player, explore dark powers or bargaining favors with the fey, or even live your very own undeath with options for becoming a ghost!

Part 1: An Introduction

A neat summary of what to expect in this book and how to use it. 

Part 2: Shadow - Your guide to the Shadowfell.

'Shadow' details how to travel to and from the Shadowfell and the various locations within. What would a desert in the Shadowfell be like? What about one of its biggest cities, filled with undead? Or a marshy battlefield filled with the aggressive spirits of a doomed elven platoon? These locations, and more, can be found within. 

With miscellaneous notes that help flesh the plane out, you can set any campaign here using the different plot hooks, a d100 chart of encounters, and a horde of NPCs that can serve as major antagonists, quest givers, or even allies. And even if a character dies, you can find rules on them becoming ghosts, liches, or vampires! 

You will also see suggestions of divine realms that powerful beings hold in the Shadowfell, and connections to planes or demiplanes. Though, perhaps one of the darkest offerings comes in the form of an expanded list of Dark Powers. The list provides 11 Dark Powers, some familiar from Curse of Strahd (but expanded upon) and some less familiar ones.

Part 3: Twilight - Your guide to the Feywild. 

With a similar level of options and flavour as the 'Shadow' section, 'Twilight' presents the Feywild in its whimsical and deadly nature. It goes into the details of the crystalline mountains of the Feywild, the sprawling underground system of the Feydark, a verdant maze filled with thorny dangers, and the expansive winterlands of the Vale of Long Night. 

You are also introduced to old and new fey courts and the archfey that serve them. Discover the two sisters that control legions of fey that are constantly antagonising each other. What plots could their war get the characters into? Or perhaps the characters find themselves to be the target of the Hunter's Wild Hunt, a worthy quarry for a terrifying foe. 

If the encounters and plot hooks don't provide enough for options, you can also look at the cold iron weapon options and fey bargains that will trick characters into losing their names, sense of self, or force them to speak in rhymes, all in the exchange for power. 

Part 4: Bestiary - Your guide to the creatures of the Feywild and Shadowfell.

Whether your campaign is in the Feywild or Shadowfell, or somewhere else, this list of plane-appropriate creatures can be thrown at a party anywhere. And better yet, almost each creature comes with legendary options and tactics to make them a formidable foe or arc antagonist. 

Will you make use of the archfey and their trickery or the utterly destructive prowess of angels of decay? The presented creatures range greatly for any flavour or playstyle.
