Original Everquest lore was the best I had ever read in any game. The 1st Fist of Light, the whole beginning of the game, player involvement, events, etc... lead to some amazing story telling. Including one of my favorite stories; the love of Nagafen and Vox... to keep them from procreating, they were imprisioned separately in Nagafen's Lair and Permafrost - kept apart.
I have the Codex of War archived somewhere... I'll see if I can dig it up. Some of the best reading ever, for a world I was able to take part in.
But the lore behind The Sleeper - just awesome, even if incomplete.

Rumor: The Sleeper is the child of Vox and Nagafen
Fact: False. The Sleeper is (according to Lore) the child of two different colored dragons, and therefore, had all the powers of both, he is not the child of Vox and Nagafen. There has never been anything mentioned about Kerafyrm being their child, and each have official histories that do not place them as the Sleeper's parents.
It has become unofficial lore that Vox and Nagafen were seperated and punished because they fell in love and it was feared they would mate and produce another sleeper. However, they're both still virgins (unless you count the countless rapings they've offered over the past 3+ years.)
Here is the Official history behind Nagafen as chronicled by Verant in EverQuest Atlas: The Maps of Myrist (page 293): "Cast out of the Ring of Scale for reasons that still remain unclear, the red dragon Lord Nagafen has resided for centuries in the fiery depths beneath the LavaStorm Mountains.
As Chronicled within the annals of the devout followers of Erollisi Marr known as The Maidens of the Rose, Nagafen, true to his dragon nature exacted a toll in maidens from the people of Qeynos, forcing them to transport one maiden a year across the continent and leave her in his cavern dwelling. This went on for many years, until a pious and beautiful maiden named Erollette - a novice in the temple of Erollisi Marr, the Goddess of Love - was selected. When Erollette sank to the ground before Nagafen, she uttered a final prayer to her goddess, asking only that her sacrifice be the last the maidens of Qeynos must endure.
Her bravery and selflessness touched the goddess, who took pity on her. As Nagafen prepared to dine, Erollisi used a golden thread to sew Nagafen's heart to his stomach, twisting his pangs of hunger into pangs of love for Erollette. Under the enchantment, he could not bear to eat her, or anything else - he was lovelorn after all. So he grew hungrier, but the more he starved the more his heart swelled in his chest and the bigger his body became, until he was so huge he could not leave the confines of his cave. He begged her to stay with him, but seeing the dragon was helpless, Erollette rejoiced and returned home to report the good news and dedicate her life to worship."
In the original Official EverQuest strategy guide (and the Kunark guide, p. 181), it was hinted that the ice giants were attempting to unite Lady Vox with Lord Nagafen (with the help of some greedy barbarians) but no mention of their past was made.
