Unlike Alisart Cleavster, who lived inside a fortified castle surrounded by knights and soldiers, Irlke Combuscrus had taken quarters into a simple hut, elevated over pillars, towns and such in the Northern Swamp were all rather simple, to move from one place to another, there were no secrets, one needed to traverse the swampy lands, often reaching up to one's waists, that was without mentioning that one needed to be rather resistant to a particular effect brought by the swamp itself, few times had invaders experienced it for they had always quickly turned back in the face of the impossible manoeuvrability.
But the swamp was toxic, one submerged within it in any shape or form would slowly be poisoned by simple contact, the northern people were resistant naturally, and could use their flames of pyromancy to cleanse themselves, all of their homes were still over-elevated well above the swamp, some sort of foam forming upon its surface from time to time.
