Knight of the Wind is the main theme of Sonic and the Black Knight, a 2009 Wii game in which Sonic takes on the role of a knight in a storybook version of Arthurian legend. Performed as a high-energy rock track, it became closely associated with that game's adventurous tone and with Sonic's sword-wielding incarnation, Sir Sonic. Fans have since reused the short opening in edits, montages and tribute videos, keeping the theme alive long after the original game. Its lasting appeal comes from that mix of speed, heroism and nostalgia.
