Flare

"Hold on."

Leonel stopped Irolana just as she was about to release the flare. 

"Hand the flare to me."

Irolana was confused but nodded in the end. 

Leonel rolled the flare in his palm, scanning it from top to bottom. 

"Let's move." Leonel said, gazing at the Titan Hyena's corpse. 

The group quickly complied as Leonel continued to observe the flare. 

If the Oryx could only see in red, that would be fine. But, according to Irolana and the others, they could also see infrared. This was a problem for two reasons. 

For one, they'd be on a time crunch. Things would be fine as long as the sun was still in the sky. But, once it set, the Oryx would gain a decisive advantage. 

During the day, the Oryx's red sight would interfere with tracking somewhat. But, at night, an Oryx might be able to pick out a human through hundreds of meters worth of foliage just based off their body heat.
