Charging onto Southshore's walls once more, the scrawny Orc swept his gaze around. At the sight of Southshore's sparse defenses, pride spread across his face. He darted away, leading his subordinates swiftly toward the gate.
When rogues used Vanish to enter concealment, they could set markers that allowed their companions to see them. This differed from the game, where the system provided that ability automatically. In this real world, there was no system, but after so many years, rogues had naturally developed their own solutions.
An army of rogues had many uses: decapitation strikes, opening gates, and all sorts of other battlefield tasks. But if the members of a rogue unit could not see one another, confusion would easily arise. They would be impossible to command and might collide with each other. To give a simple example, if they infiltrated a city and encountered a guard, they would need to kill him before proceeding. Naturally, some rogues would move forward to deal with him.
It was fine if they could see one another. If two rogues were already approaching the guard, the others would stay back. If they could not see each other, a whole crowd might rush over at once. Rogues could turn invisible, but that did not mean their bodies were hidden in another dimension. If someone touched or collided with them, they would still become visible. Confusion could easily break out, and they might accidentally injure their companions.
Thus, markers had come into use, allowing companions to see each other. This was also why Rex had felt comfortable placing a Sentry Ward on the wall, without worrying that these rogues would realize they could be seen. In a rogue's eyes, both they themselves and their companions appeared visible, so they remained completely unaware of the Sentry Ward.
