Heroes of Laketown
One of the greatest Dragons to survive the destruction of Angband, Scatha the Worm roamed Endor’s northern wastes throughout the Second Age. As the eldest surviving offspring of Glaurung, he was the preeminent Cold-drake in the North. He later made his lair in the Grey Mountains,where he awoke around T.A. 1625.
Scatha considered himself the lord of the range when the Dwarves of Durin’s Tribe began mining in the region in T.A. 1999.Scatha slew a number of the Naugrim and built quite a treasure-hoard prior to the arrival of Durin’s Folk. However, when the wealthy Dwarves from Erebor (the Lonely Mountain) entered the Ered Mithrin, he struck quickly. The Great Cold-drake remembered his father’s defeat at the hands of the Dwarves of Belegost and feared that the stalwart intruders would claim his domain. So, the foul Worm attacked the Dwarven mine at Silverplunge, where he killed the inhabitants and captured a vast cache of treasure.
