Getting A Map

By the city wall. 

Void was the first person to try to teleport into the city. The reason Grey told him to go first was because he was not only better with the space element, but given his size, he would be able to evade any problems in case any arises. 

'You can come, there's a bit of resistance when making a space tunnel, but you should be able to make it through,' Void's voice echoed in Grey's head. 

'Alright,' Grey nodded before trying to create a space tunnel. 

Surprisingly, he failed in the first attempt which shocked him. Even though Void told him there was a little bit of resistance, he didn't think it was this strong. 

He tried opening it again, but the result was just like the first time. He was unable to open it. He didn't give up immediately, trying it four more times, but the results were the same, he was unable to make it. What was more annoying was that his space essence reserve was draining at an unimaginable rate.
