My Life in Another World Is Sickening

Hum, now aliased under the guise of Captain Freimann of the Crimson Snakes, has once more risen as leader of mercenaries in the world of Calemil, where the weather is locked to one's nation, the Gods demand true devotion for their miracles and mages can make the difference between holding out in a siege or being forced out in a matter of minutes.
His greatest challenge has yet to come; for the battlefields he faces may require wits, or just patience, but the unending doubts and questions within his mind need to be put to a final rest...like the ghosts of a legendary treasure, and the honeyed words of someone who is clearly not what it seems.
