There was more than one entrance to the Second Layer, and from what Warden observed, the forsaken had taken control of them all. He embarked on a scouting trip of his own when most people were asleep or resting. Utilising his anti-gravity scripts, the journey barely took a couple of hours, although he found signs of goblins and orcs within half an hour.
They were organised in small teams, on the lookout to hunt for any humans they could find. Warden himself encountered five such teams, despite not seeking them out. The security at the entrance they had established was on another level. Hundreds of them, goblins, orcs, and trolls alike, lined up around the small warp gate.
Other than over a hundred goblins and orcs in similar numbers, what made Warden's skin crawl were the dozens of trolls. More could be hiding somewhere else. And in the second layer.
Clearly, they were taking this very seriously.
