Echoes of a Shattered Age by Ramón Terrell

Evil never sleeps.Technology is dead, and the world grows wild with dangers born from legend. Kenyatta and his friends brave unknown horrors to stand against a massive horde of the most feared monsters in the abyss. Demonic enemies appear out the shadows, and five warriors unite to stop the tide of evil before it washes over the land, and envelopes the world in darkness.
