Dragon Eclipse: Foray into the Shadow RealmsExpansion

From BoardGameGeek:

You'll embark on a journey into the Shadow Realm, discovering new landscapes, marveling at a moonless sky, and uncovering the mysteries of the creatures that dwell in the dark. The Foray into the Shadow Realm action takes place after the end of the main Dragon Eclipse story. This add-on brings you three scenarios, adding +10 hours of gameplay to your Dragon Eclipse experience! You'll face off against six brand-new Mystlings, each wielding unique abilities and special cards to challenge you. This expansion also extends the Roguelite mode by introducing a fresh map and a special set of cards that will allow you to use the Mystlings from this add-on in the Core Box Roguelite mode. Includes almost 200 cards, 50 Adventure Journal pages, over 7 location maps, four new booster packs, and more.
