A weathered treasure map painted on cracked parchment, top-down view filling the frame. The island is shaped like a sleeping sea serpent with three jagged coves, hand-drawn in sepia ink with subtle umber and ochre washes. Tiny pictographic icons mark a skull-shaped cave, a coconut grove, a shipwreck named the Halberd, and a dotted red trail leading to a black X labeled "Hark Ye Here". A wind-rose compass sits in the upper-left with cardinal letters "N E S W", and a sea monster coils in the south-east waters spitting curled steam. Edges are burned, torn, and stained with circular tea rings. Hand-lettered serif typography reads "Isle of Cinder Bones" across the top in faded ink. Tiny ships sail along latitude lines drawn as faint dashed arcs. Lighting suggests an oil lamp from above, casting a soft warm vignette toward the corners. The texture shows visible paper fibers, ink bleed, and quill scratches. Color palette: brown, cream, oxblood red, and ink black, with one faint teal stamp resembling a crown in the corner.
