"what the hell, why can't I set myself free from this damn wood?".
Caius struggled to get the vines that were restraining his movements off of him, by pulling it toward him and attempting to uproot them from the walls they are attached to.
He was met with surprise when he noticed that no matter how much he pulled, or the force he exerted in pulling the vines, it did not budge from its position one bit.
"what are they made of to be this strong?".
He made one last attempt that proved futile. The flame coming off of his body also did no damage to the vines. It absorbed the flames from Caius body and sucked it all into itself, using it as nourishment for its growth.
This came as a shock to Caius. The natural order known to all, is that wood will always be weaker than fire, but this specific wood tying him down, was unbound by the natural order, and refused to succumb itself to its supposed natural elemental adversary.
