Gremlik was forced to agree with Erlik. The Grendel Dryad started yelling orders while inwardly cursing the human race for the umpteenth time. If it wasn't for them, he would have never left Jiera and he would still retain the role in the local undead society he had fought so long to achieve.
After the fall of the human race, there was no more strength in numbers, only weakness. More people meant more mouths to feed, making the damages on the local flora too extensive and without even someone to use as a scapegoat.
No more afraid of the humans' interference, plant folks and Fae had started to band together, hunting down the undead that had no place to hide.
To add insult to injury, the undead couldn't even run away from their oppressors since they were also their main source of food.
