The forest that contains and defines Rilyn, spreading across the northeastern slopes of the Screech Peaks and down toward the Fernius Sound coast. Puma Wood is old-growth forest — massive trees that have stood for centuries, their canopy creating a green twilight below. The Splinkreen have lived here since their transformation, building their city among the trees rather than clearing them.
The forest is named for the large cats that once hunted here, though the pumas are rarely seen now. Whether they've retreated deeper into the woods or simply grown more cautious around the Splinkreen is unclear. The name persists regardless.
