The Jeniyan. Book Two of the Necropolis Series, #2

The Shetani, a man hating tribe within the underworld, an ancient realm replete with prehistoric animals and medieval technology, aims to annihilate an old rival called the Jeniyan. The Shetani's wrath is evoked after they learn the Jeniyan allowed a body of men seeking refuge a stay within their territory, but little did the men know why the Jeniyan received them with open arms. Little does the Jeiniyan know the men are wanted for attempting to exterminate the Shetani's leader, the dark lord Nyeusi, but also for being in possession of a coveted magical jewel.
That jewel is the Necropolis. This is the second book of the Necropolis series, a dark fantasy adventure in which its heroes and heroines who believed life ended when they died learned this was not so. In this sequel, the Shetani, their misanthropic foe, once again works in concert with the necromancer, the chief practitioner of black magic and sorcery there, who is also indifferent to the fallen men's plight.
