Was from Erathdawn: The Theran Empire. The Passions made a pact that no dragon ever got a feet on Creana (old name for parts of now-days egypt). However, just an ingame text from Theran Empire, page 43:
On the Origins of Creana, -In the words of Man-ot-krel,High Initiate of Pharon Zhem-ka-tep II:
[spoiler]Hear now the story of the Creation, long known to the Priests of Gez.
On the day before the first day, there was nothing.
On the first day, there was Earth and Sand. The Earth and Sand were Amaz-Chelk, the Red Passion. Alnaz-Chelk was angry and alone. He burned.
On the second day, there were the first Name-givers: the dragons. The dragons flew in the sky. Their flying made the Blue Passion, Ozul. The dragons attempted to land upon the Earth and Sand, but Amaz-Chelk burned them.
So they took to the sky again and asked Ozul for help. Ozul, aloof, refused them.
On the third day, the dragons created the other Name giver races: the jackalmen, dwarfs, elves, orks, trolls, windlings, humans, obsidimen and t'skrang. They told the new Name-givers to walk upon the Earth and Sand, to cool Arnaz-Chelk's anger. Amaz-Chelk burned them up, and thus mortality came into the world. The first o the jackal-men to be slain became the White Passion, Sanep, guardian of the gates of the dead. He left this world and journeyed until he found the Lands of the West, a world for the dead to live in.
On the fourth day, the dragons cried. This day marks the only time that dragons have shed tears. Those tears fell onto the breast of Amaz-Chelk,
and they became Ureth, the Great Mother River. Ureth cooled the anger of Amaz-Chelk and demanded that Name-givers be given the right to live
upon the Earth and Sand. Amaz-Chelk agreed, provided that the dragons pay a price for disturbing him. He would go to sleep, and the dragons would also go to sleep, deep within his embrace. Before going to sleep, the dragons would be permitted to lay eggs, which the Name-givers they had created would take to distant, imperfect lands.
But from that day forward, no dragon would be allowed to walk the sands of Creana, the perfect land, or fly in the clouds of Ozul, the sky above the perfect land. Woe betide those who disturb the sleep of Amaz-Chelk or the dragons he embraces.
On the fifth day, Ureth, the Great Mother River, invited the remaining Name-givers to live along her banks. She gave birth to wheat and to barley. The Name-givers planted these seeds in the dark, rich soil. They sprang to life, as did two children dreamed by Amaz-Chelk: Tabru and Malek. Tabru was the Black Passion, the Passion of Wheat and Barley. Malek was the Multicolored Passion, the Passion of Vengeance and the Desert.
On the sixth day. Malek and Tabru each courted Ureth, to take her as wife. Ureth chose Tabru, for it is natural that the fertile river should choose the seed from which crops grow. Malek was angry and slew Tabru, then threw his dismembered body at Ureth's feet. Malek then retreated to the desert, where to this day he remains a menace to Name-givers and Passions alike[/spoiler]
What happens when a dragons siffs again Creana sand? Nobody knows. But I think nothing the sleeping dragons would like to happen.
Found an old thread:
Why are there no dragons in egypt?
