Pentaworld, continent of Nexal, year 1420.

The war between the Deson Bloc, on the one hand, and the Empire of the Hundred Phoenixes, on the other, rages in the continent of Nexal.

The impregnable Idekrad Stronghold is the last obstacle between the Empire's attack fleet and Navan City, the largest metropolis on the continent, the last one still under the control of the Deson Bloc.

The executors, beings with immense powers, had been created centuries before to serve humans, but now they are free and have taken the field alongside the Empire: one of them has been sent to take Idekrad.

"The Night of the Leviathan" is the first story in the series "Executor Hunter", set in the dystopian steampunk universe of "The Pentaworld Cantos" created by Atra.
