Having contracted a recent case of the flu, Auryuu had time to kill and he didn't feel like staying at home in bed, he just wasn't that kind of person. Like many he would go and search out the rebellion, he did not know whether he should join or stay in the gotei 13, but he at least wanted to check it out. He had hiked for 4 days straight, no one would notice his absence so he felt safe knowing it was just him on the empty lifeless trail.
Finally, he reached the forest. It was foggy and he could hear sounds rattle the trees inside. All life seemed to have fled from the once lively forest. Birds no longer flew, caterpillars no longer crawled, and wolfs no longer howled. The forest was the embodiment of strange and creepy rolled into one oddity.
Auryuu drew closer as he instantly pushed out the scrubs that he had been crouched by to see further in. The forest was still very clouded, having the fog blocking his vision and also the trees to obstruct it too. It was getting cold, he realized he would have to make a camp, he couldn't afford to just walk in there and expect hospitality, he would wait until morning to touch base. Auryuu slashed up a nearby tree with his katana and quickly stacked pieces of the wood into a pit. He whispered in a soft voice, "Fireball", as he did the kido launched from his hand impacting the wood and starting a bright blaze.
Auryuu began to unpack his things and started to hitch his tent.
