And Don Pablo's abode was really and truly a four-roomed cottage, where he lived along with a simple-minded old Cornish woman of sixty, who attended to his few wants. Enistor knew that Narvaez was immensely rich, and wondered why he should live so penuriously and humbly. But the man was almost wholly devoid of desire for things which mankind covets. He ate and drank sparingly: he cared nothing for society: his dress was plain but neat, and he was too much taken up with study to entertain. Narvaez, as his neighbour soon found out, was consumed by a passion for power: not that kind of power which is displayed openly by royalty or politicians or merchant-princes, but the secret power which sways the destinies of individuals and nations without apparent sign. For this he studied day and night, and crossed constantly the boundaries between the worlds visible and invisible. He obtained no physical benefit from the exercise of such command, but the passion of hidden sovereignty satisfied his soul, and that was all he cared about. He had long since risen above the sphere wherein the virtues and vices of men dispute pre-eminence, and lived above the healthy necessary turmoil of ordinary life to reign in solitude as a cold, calm, intellectual and merciless tyrant, doing evil because it gratified Self. He disobeyed the law of love which is giving, and isolated himself in a kingdom of his own, which his desire for rule had cut off from the great empire of God. His sole connection with men and women was to destroy their protecting will and make them slaves to his whims. In this way he acted with regard to Enistor, else he would not have taught the man anything about dark magic. But Narvaez knew well that Enistor, possessed of as fierce and unscrupulous a nature as his own, and almost as powerful a will, would never be a slave. Consequently he was obliged to act cautiously in his association with him. Enistor, if he became too learned in forbidden lore, might well become Don Pablo's rival, to dispute the bad sovereignty which the Spaniard loved. As a matter of fact Narvaez would not have meddled with the Cornish squire at all but that he knew that a common danger menaced both, which Enistor, through his daughter, might avert. Narvaez was clever and powerful, and wholly given to self-worship, but he was by no means omnipotent, and at times it was necessary to defend his position. Thus by the offer to teach Enistor how to realise his ambitions, he managed to make the man more or less obedient: but there was always the danger of revolt should Enistor learn too thoroughly the laws of the invisible world, which interpenetrates the visible. Don Pablo, however, was content with the position of affairs, as his pupil was not yet strong enough to measure swords. And before he was, the Spaniard hoped to secure his ends and leave Enistor in the lurch.
