Question about ASOIAF.

[Ser_Hakim_Dayne]

The mere existence of dragons in A Song of Ice and Fire amplifies and increases the power of magic throughout the world :

The mage was gesturing, urging the flames higher and higher with broad sweeps of his arms. As the watchers craned their necks upward, the cutpurses squirmed through the press, small blades hidden in their palms. They relieved the prosperous of their coin with one hand while pointing upward with the other. When the fiery ladder stood forty feet high, the mage leapt forward and began to climb it, scrambling up hand over hand as quick as a monkey. Each rung he touched dissolved behind him, leaving no more than a wisp of silver smoke. When he reached the top, the ladder was gone and so was he.(...)."Half a year gone, that man could scarcely wake fire from dragonglass. He had some small skill with powders and wildfire, sufficient to entrance a crowd while his cutpurses did their work. He could walk across hot coals and make burning roses bloom in the air, but he could no more aspire to climb the fiery ladder than a common fisherman could hope to catch a kraken in his nets".(...)."And now his powers grow, Khaleesi. And you are the cause of it."

"Was it not you who told me warlocks were no more than old soldiers, vainly boasting of forgotten deeds and lost prowess?" Xaro looked Troubled. "And so it was then. But now? I am less certain. It is that the glas candles are burning in the house of Urrathon Night-Walker, that have not burned in a hundred years. Ghost grass grows in the Garden of Gehane, phantom tortoises have been seen carrying messages between the windowless houses on Warlock's Way, and all the rats in the city are chewing off their tails. The wife of Mathos Mallarawan, who once mocked a warlock's drab moth-eaten robe, has gone mad and will wear no clothes at all. Even fresh-washed silks make her feel as though a thousand insects were crawling on her skin. And Blind Sybassion the Eater of Eyes can see again, or so his slaves do swear. A man must wonder." He sighed."These are strange times in Qarth. And strange times are bad for trade."

Yes, you have secret spells; how splendid. What of them ?" "They, hmmmm, seem to be working better than they were." Hallyne smiled weakly."You do'nt suppose there are any dragons about, do you?" "Not unless you found ne under the Dragonpit. Why?" "Oh, pardon, I was just remembering something old Wisdom Pollitor told me once. when I was an acolyte. I'd asked him why so many of our spells seemed, well, not as effectual as the scrolls would have us believe, and he said it was because magic had begun to go out of the world the day the last dragon died."

"but he has no more proof of dragons than Mollander. Just more sailor's "stories". "You're wrong", said Leo. "There is a glass candle burning in the Mage's chambers."(...) "Dragonglass," Pate said. "The smallfolk call it dragonglass." Somehow that seemed important. "They do," mused Alleras, the Sphinx, "and if there are dragons in the world again..." "Dragons and darker things," said Leo. "The grey sheep have closed their eyes, but the mastiff sees the truth. Old powers waken. Shadows stir. An age of wonder and terror will soon be upon us, an age for gods and heroes."
