Trolls

Trolls were a very large and monstrous, and for the most part unintelligent, humanoid race inhabiting Middle-earth.
== History ==
Melkor created trolls before the First Age. They were very strong, but turned into stone in sunlight. Many trolls died in the War of Wrath, but some survived and joined the forces of Sauron, the greatest surviving servant of Morgoth. In the Second and Third Age, trolls were among Sauron's most dangerous warriors. He created the Olog-hai, which were smarter than earlier breeds of trolls. While most trolls could not bear exposure to sunlight without turning to stone, the Olog-hai apparently could (to the same extent as orcs); this attribute was mentioned as making them particularly dangerous.
During Bilbo's quest to the Lonely Mountain, trolls were known to speak with thick Cockney accents, specifically three hill trolls who had dwelt on the Ettenmoors and moved down to the Trollshaws . They turned to stone when exposed to sunlight, for stone, is what trolls were originally made of. They enjoyed eating anything they could get their hands on. While threatening, the trolls in The Hobbit serve as a comic element. They even had normal names: Tom, Bert, and William (Bill) Huggins (the only one with a given surname).
During the War of the Ring, Frodo and the Fellowship encountered cave trolls alongside various orcs within Moria. Boromir's sword recoiled off the scaled hide of one troll. As things seemed perilous, however, the trolls fled (although this was due to the approach of the balrog, Durin's Bane). Sauron used Olog-hai in the Siege of Gondor and Battle of the Pelennor Fields. In the subsequent Battle at the Black Gate, the hobbit Peregrin Took killed a large Olog-hai troll with his barrow-blade. As a result of the One Ring being destroyed, the Black Gate collapsed into ruin during that battle. Most of the trolls present at the battle were killed, and the others are known to have fled.
