The setting-Age of Sigmar

When the Old World was destroyed during the End Times, Sigmar clung to the core of the world and escaped the Chaos somehow. On his journey, he met the Great Drake Dracothion, who showed him the way to the Mortal Realms, and the Age of Myth began. It's a world made up of eight realms/sub-worlds, each one aligned to one of the eight winds of magic, connected by so-called realm gates.

There he ruled along with the other gods, mentioned are Gorkamork, Tyrion and Grungnir. But as the gods eventually became at strife, Chaos gained a footprint in the Mortal Realms, and enslaved all the sub-worlds except for Azyr, the Celestial Realm. There Sigmar barricaded himself with the refugees of the Old World, rallying his strength in its capital Azyrheim. He created the Stormhost Eternals, warriors filled to the brim with the holy magic of heaven. Immortal and of super-human strength and build, they are clad in armour of Sigmarite and capable of shooting lighting bolts with their magical weapons. His army of Eternals is said to be vast, and now the time has come to free the other realms from Chaos once and for all.

Of the other races, little is known yet. There are four great alliances.

Order – Sigmar and his forces, the Duardin (Dwarfs), the mercenary Red Slayers (Dwarf Slayers?), Aelfs (Elves) and the mysterious Seraphon (Lizardmen?). Empire and Brettonia are not mentioned, apart from the "refugees of the Old World" wink before.

Chaos – Warriors and Daemons of Chaos, as well as "brayheards" (Beastmen) and Skaven.

Death – Deathrattlers and Deathwalkers are mentioned (Skeleton Warriors and Zombies?), as well as Soulblight Vampires and Nagash himself.

Destruction – Orruks (Orcs), Grots (Goblins) and Ogors (Ogres), also hints about all sorts of other beasties.
