Steam

Three out of the four portals were encountering severe pushback from the people of the realm, by its wildlife, and even its plantlife, it seemed like there was nothing that wasn't willing to get in the way of the invasion by the undead.

The fourth portal had landed in luckier spot, a small grove within one of the denser and darker forests of this realm, near the edge but not too close, in proximity to small rocky biomes covered in warm ponds that exuded constant steam, region that was mostly populated by smaller beasts and more prominently, by the yrztuls, small, fennec fox-like animal, the colour of their fur varying strongly from one individual to another.

They had established themselves by taking root in a region without much ressources and other beasts, preferring to feast on fruits from the few trees that grew in this heated environment where one couldn't rely on sight due to the constant steam rising day and night.
