Opening the System interface, Zain ensured that his Horde members were safe. He observed that they were still on the map, their hunger levels were good, and it looked like there was no trouble in sight, at least at where they were.
Since they were in the city, there were plenty of apartments and rooms that one could hide in, making the area somewhat safe for them. Food was the only problem when leaving them for a few days like that. However, Zain knew that making the stay for one day wouldn't be a problem.
