Due to them being wary of Ember's mines, their expansion became a lot slower.
It took them roughly an hour to finally completely secure the area they needed to hold their entire army. As soon as they completed the perimeter, they stood around the borders, keeping watch over the incoming demons and clearing them.
As they stood on standby, the portal then began to spew out the other members of the army. Batch after batch, their tamers began flooding out and moving out of the way immediately.
It was as if they already had a location they had to stand on beforehand, as they ran without even a hint of hesitation.
"But running in a large group is a bad choice."
Ember did plant landmines there, but who said it was only one type?
*BOOOM!*
