The Fire Rift is a stronghold of a race of demons waging an eternal war. However, like all the peoples of a world burning in battle... Every little thing can be important in a confrontation, let alone the legacy of the ancient demons, by whose forces the Rift was created. Ogar, a demon from the Far Search - a reconnaissance and sabotage structure of demons - receives from an informant the key to the heritage of the ancients. But this key turns out to be tied to the one who first activated it. Now the authorities have no choice but to send Ogar at the head of a small group in search of magical treasures. To pass through the lands of enemies, snatch mysterious valuables from under the noses of the inhabitants of the Underground Limit and return “with a shield” - what a challenge for an ambitious and cynical demon?
