Jayce was shook. Despite knowing that he was currently experiencing a vision, there was not one part of the experience that made it feel this way.
All his 5 senses were telling him that he really was here, inside this epic battle. Thankfully this was not the case, as Jayce knew that he would not even last a few seconds embroiled in this hell.
The problem was, he did not know how to remove himself from this vision. There should be a reason why he was taken to this place, and only once that reason was revealed would he be able to leave.
From his earlier suspicions, he assumed that it was the dark sword that had transported him here, so what better option did he have than to follow its journey.
Jayce looked around his vicinity, yet the battlefield was too chaotic to track down Rubick in all of this mess. Clouds of dust and dismembered bodies littered his surroundings, making it almost impossible to see past 5 to 10 meters in front of him.
