Arus's eyes light up as he saw the helmet, at last some trace of the knight. He glanced at the obvious tracks leading into the woods. Could those be of Holliander's chocobo? Was he chasing after that dark creature that had somehow made the risen more powerful and then remained unaffected by that insanely powerful spell? His horse neighed and pranced clearly nervous just being in the same area.

 He looked back at the city reluctantly, realistically speaking, he should grab the helmet and ride back to the city in order to organize a search party and then find him. But after that it might be too late, and he couldn't even guarantee that he could gather enough people to come with him. After all Arus was part of the group that would no doubt be viewed as having brought this trouble in the first place and, as he had already seen, the locals so far dealt with at least some dislike towards them. 

He grabbed the helmet and tapped his horse with his heels causing it to begin riding into the forest, albeit somewhat reluctantly. If Holliander was out there, or worse fighting that evil creature, he had to help in any way he could. Arus drew his sword as he followed the tracks, expecting the worst.
