Smaug

In The Hobbit, by J.R.R. Tolkien, Smaug was a greedy, reddish-gold dragon who laid waste to Dale and captured the Lonely Mountain and all its treasure. He was killed by the Black Arrow of Bard the Bowman.

Smaug is also the name of a Merc[?] and Dikumud[?] derived MUD online game program. Presumably the name comes from the Tolkien reference.
