Gaining permission from the older guard, the other one waves a hand to the ones up top so they can open the gate as it does for two newcomers to enter. It took just a second for Bolla and Xalroz to thank the guards and say their goodbye when going forward.
Once the gate closed again they kept on walking forward getting little looks here and there mostly at the Drow elf walking beside the warrior-looking woman who did not want to make any such eye contact with her worrying that they would somehow anger the woman.
Funny that Xalroz finds the moment of him and Bolla just acting out as just two travelers at first and yet their real purpose is to find the weakness of this town and use it to their full benefit just to invade this place.
