Well there will only be 6999 steps, wasn't one of them destroyed by a dragon? If you count the place where a step once was as a step there will no doubt be 7000.
The second song of King Wulfharth glorifies his deeds in the eyes of the Old Gods. He fights the eastern Orcs and shouts their chief into Hell. He rebuilds the 418th step of High Hrothgar, which had been damaged by a dragon. When he swallowed a thundercloud to keep his army from catching cold, the Nords called him the Breath of Kyne.The Nords do not believe in creation. "We always were," they'd say. However, their Song of Return is anologous to a creation myth. The Breath of Kyne calls the Nords, so they aren't erased from pattern, in the Kalpa turning. If Clan Ald Eats the World, Man is wiped from the pattern of possibility, and life returns to the immortal days of mythical Aldmeris. Or so the Altmer believe. Keeping the steps is vital. They fortify the pattern, for the Nord's Hero to make the mythic transition, over the layers of the Cosmic egg, to the Sky. From the Sky, he returns with the power to kill their enemy, Alduin. "Eastern Orcs" is a repeated reference to Dwemer. Their chief is Dumalacath the Dwarf-Orc, whose Tonal Architects erase the Dwemer from the Heart of the World. The Heart belongs to Wulfharth, anon Lorkhan.
