'first things first, I need to get out of here and find myself a better terrain for a more effective confrontation with him'.
His current surrounding is very shallow, like a tunnel with only one passageway out of it, and he, is at that passageway.
He had Caius below him, while he is above him. Such settings will not benefit Orun going up against the current Caius.
He knew he was going to be faster, stronger, fiercer, and he is at risk by being in a space so tight, not knowing how much distance the current Caius can cover, or how explosive his current power output is set at.
By finding himself an open area to stay in and prepare for his to the death fight against Caius, Orun would be giving himself enough space to make decisions, and multiple choices to reside in, while also giving himself the chance to have a better read on Caius's current power output.
Orun got out of the tunnel, staying in the open ground surrounded by trees, where he awaits Caius to come and meet him at.
