Trolls are huge hulking beasts. Fat an ungainly, their legs seem too small to bare their weight. They have long arms, are thickly muscled and have giant, wide fingers. They have large tusks sprouting from their maws, shorter on the top and bottoms of their wide mouths. The tusks on the lower jaw continue to grow as a troll gets older and often grow into the creature’s face. They are shaped, cut and sometimes decorated with carvings. Very old trolls have very large, often bent and chipped tusks. They use these tusks in battles against one another, roaring at each other with mouths agape. Though they occasionally try to gore each other, a battle usually ends with the troll with a wider yawn and larger tusks victorious. They are ferocious creatures, bent upon destruction.
