You know. That guy. The source of all evil in Arda (allegedly) (the Fëanorians certainly tried).

"Death to light, to law, to love;
cursed be moon and stars above;
may darkness everlasting old
that waits outside in surges cold
drown Manwë, Varda and the sun;
may all is hatred be begun
and all in evil ended be
in the moaning of the endless Sea!"
—J.R.R. Tolkien, The Lay of Leithan
