Unforgotten is an expansion with 2 dual faction heroes that worship both Taulot and Kurumo at once, helping you mix red and green heroes together. In gameplay terms, when these heroes take a worship action you resolve both the green and red worship in any order of your choice. This is the third release of the dual faction cycle started with Stormsear and Winterdeep. Unforgotten features a new type of power card with two runes at once that can only be played by heroes with both runes. There are 5 blue/green and 5 red/green power cards. The same amount of blue/yellow and red/yellow cards will come with Untamed, the last expansion of the dual faction cycle releasing in 2022.
