A monster Knight chess piece, depicted as a quadrupedal beast with armored plating. Its material is a fusion of gnarly, gnarled tree bark and razor-sharp, dark green crystals, creating a coarse, splintered texture. The colors are earthy browns and deep forest greens, with vibrant emerald highlights. Its posture is low and aggressive, ready to charge, featuring a snarling, wolf-like head with jagged teeth, feeling surprisingly brittle yet immensely strong.
