The thief hadn't noticed anything happening at first, not feeling the vines until his adversary had disappeared again. It took him until he attempted to stretch his legs to notice something was wrong. Feeling resistance, he spotted the vines poking through the ground. "I can fix that easily enough." Leaning forward, he grabbed his dagger and began to cut apart the binds.
He had just snapped the final binding when Fin's latest attack struck. He sprang to his feet with a howl and turned around to find, as he expected, nothing. The man winced as he ripped the quills out of his rear and spat a renewed series of curses.
His mouth practically worked on its own as his mind began to run the possibilities over. Somebody had picked a fight with him, somebody who had nothing to gain except perhaps satisfaction, somebody who seemed to be able to get at him from underground and the sky, somebody who would use the spikes of a porcupine as a weapon. Lerrok wasn't exactly well versed on the subject, but there didn't seem any clear answer besides the one- some sort of fae.
Lerrok growled. "Alright then, if I can't catch it to make it swallow those coins, then I'll just have to settle for the next best thing." He rummaged through his gear until he came across some flint, tinder, and one of the torches he carried in case he ever needed to travel at night. He stormed towards the treeline. "Alright, whatever manner of nuisance you are, I'm going to give you till the count of ten. Show yourself or I start burning." He was bluffing of course, he didn't really want to kill everything inside, even the pest, but he certainly looked furious enough to mean it. Some part of his mind reminded him that even if the assailant showed itself, he wasn't exactly sure what he'd do about it- he ignored it.
