Magic and Mayhem was designed by Gollop as the next incarnation of his successful Chaos video game concept, involving the same mythical wizard combat.

The wizard and any summoned creatures are controlled, as in most strategy games, by dragging selection boxes and using the mouse buttons to interact and issue orders.

Magic and Mayhem is set in three mythological/historical realms; Albion, Greece and Avalon, covering Arthurian, Greek, and Celtic themes respectively.

On his journey through Avalon, he meets allies including Twigkindle the brownie king and Percival the knight, the latter of which joins Cornelius in return for his aid in finding the Grail.

After an epic battle with the resident baron-wizard Bertilak, Cornelius finds and frees his uncle Lucan, only to confront the game's main antagonist, the Overlord.

After the battle, Cornelius wants nothing more than to return to the mundane world with Lucan, but it is revealed they must find a specific portal to do so, so their quest must continue through a magical gateway into Greece.

Arriving in Greece, Cornelius continues to travel looking for a way back home, but encountering yet more hostile wizards and evidence of the Overlord's misdeeds.

Cornelius continues his quest, gathering Arthur's loyal knights and attacking Camelot, freeing Ariadne and Lancelot and retaking the castle.

Cornelius and his allies eventually meet the Overlord at Dinas Emrys, discover that he is Merlin, defeat him, and return to the mundane world.

The background music for Magic and Mayhem was composed by Afro Celt Sound System,[7][8] and was highly regarded by game reviews.

[4] As stated by Simon Emmerson, founder of the group, in the game's manual: The Mythos Team were drawn to The Afro Celt Sound System because our last record (Vol.

1: Sound Magic, Real World Records CDRW61) had the slow builds and epic soundscapes they felt would work wonders in a multi-media context.
