If they continued straight down, the next territories would be the terrain of violent monsters, so they didn't have the intelligence to investigate their enemies or know when to retreat or advance.
Thanks to the dwarf skeletons advancing their work, the army was able to resume the march sooner than expected and with the manticore territory empty, they headed straight for the territories of the violent monsters.
It took less than two days' travel to reach the territory when marching at full speed, as Athos forced the skeletons to run the entire way. Human skeletons were carried by monsters, while demihumans were fast enough to keep pace with monsters.
The wyverns who went ahead reported that the monsters they would encounter in the next territory were a pack of acid wasps, wasps a meter long each.
