Darkside of Xeen concludes the story arc started by
Might and Magic Book One: The Secret of the Inner Sanctum – the interstellar campaign against the Ancients' renegade creation, Sheltem. Picking up where
Clouds of Xeen left off, the adventurers take King Burlock's advice and follow Prince Roland's trail to the other side of the world, where they find the rogue Guardian of
Terra has already conquered its inhabitants, under the pseudonym of "Alamar" (the name of the king he impersonated on VARN in
Might and Magic I). Meanwhile, the Guardian of the Darkside – the
Dragon Pharaoh – contacts his rebel allies one by one, discovering that all have been imprisoned or converted to Sheltem's cause. In a desperate gambit, the Pharaoh sends a dragon hatchling into the night skies of the Darkside, carrying a command orb holding some of his power. The hatchling is killed in flight by a magical bolt, directed by Sheltem, from his castle. The orb survives its fall to earth and is discovered by the adventurers. Passing through the city of Castleview, they scale the tower of the
elven wizard Ellinger Hofenhager, an ally to the Pharaoh. Because Alamar moved Castle Kalindra, seat of power to the eponymous Queen of the Darkside, out of phase with the physical realm, Ellinger instructs the adventurers to gather enough energy discs to power a spell capable of restoring it to reality. They travel the realms of the Darkside, liberating the city of Sandcaster from Alamar's
sorcerer agents Morgana and Xenoc, collecting discs along the way. With Castle Kalindra restored by Ellinger, the heroes enter, only to find that Queen Kalindra has been defeated and captured by one of Alamar's minions, the
vampire Count Blackfang. Invading Castle Blackfang with the aid of the
knight Ambrose and his
griffin, the adventurers slay the Count only to find Kalindra has been turned into a vampire. They restore her from undeath using her lost crown's powers, and with her aid are able to reach the Ancients' pyramid where the Dragon Pharaoh resides. After they return the Pharaoh his command orb, he explains that Alamar holds the Ancients' Cube of Power, which enables him to direct the dual-sided nacelle world of XEEN (Xylonite Experimental Environment Nacelle) through the Void. Using the Cube, he plans to land Xeen on his homeworld, Terra, and continue his rampage against the empire of the Ancients. The Pharaoh reveals that when Alamar fell to Xeen in his "shooting star" (in actuality an escape pod), a second pod also landed, but was snared in the volcanic mountains of the northeast. Investigating this second pod, the adventurers discover Corak, Sheltem's nemesis from
Might and Magic II and
III. Corak instructs them to somehow teleport him into Castle Alamar so that he can put an end to his old enemy once and for all. The Dragon Pharaoh leads them to the airborne city of Olympus, where they obtain a Soul Box. Transferring Corak's essence into the Soul Box, they fight their way to Castle Alamar and, battling Sheltem's hordes, manage to reach his throne room. Casting the Soul Box inside, they retreat as Corak emerges to battle his old foe, though the two are evenly matched. After a destructive skirmish, Corak is defeated, but compels Sheltem towards him and
sacrifices himself, initiating their dual
self-destruct command. The resulting explosion of power destroys both Guardians along with Castle Alamar, bringing the threat of Sheltem to a bittersweet end. ==
