Xervas was still bitter about the fact that he hadn't been able to kill the one rat, and it had been a cycle since. He'd killed every other one since then, but that one lost battle was weighing him down. The lammergeier couldn't let the one mistake go. But, over time, he had concluded that it was because he was young and inexperienced then-- he was better now, he had improved. He could likely take on anything thrown at him at this point.
Nevermind, of course, the fact that he couldn't fly and hadn't taken down a larger animal. But he still felt confident. Yes, he could quite easily kill a larger Lesser Gembound, but he had no reason to. Or maybe he did have a reason, even if that reason was just to prove that he could.
He was slowly walking through the muddy soil, lost in thought. The feathers around his feet seemed to be permanently stained the color of muck, but Xervas did not care. Until, that was, he tripped on a small rise; he inevitably fell into the filthy water. He quickly got up, but he did let out an indignant screech. Now the bird was entirely covered in filth, and that was a different story.
