The frozen stone of the ground was harder than our armor and best only by our will to survive the forest. The trees prepared to attack. We cowered as their thistle blooms opened, waited for fate to wash us out of this world, but the endless flood of thorns never came. They could not drive their roots through the earth. Being cut off their source of life, we gave them the rain they deserved – a hurricane of burning arrows. Hope sprout from a forest ablaze, screeching, staggering and falling. It was time to strike back, time to smash our axes deep into the wood and to fill the chilling air with splinters. Bowyers, carpenters, shipwrights as myself – today we were all soldiers.
— Through the ruthless Green Plague, Chapter 3, Arthur Sprayh
