After that Lludd had shown his brother the cause of his errand, Llevelys said that he himself knew the cause of the coming to those lands. And they took counsel together to discourse on the matter otherwise than thus, in order that the wind might not catch their words, nor the Coranians know what they might say. Then Llevelys caused a long horn to be made of brass, and through this horn they discoursed. But whatsoever words they spoke through this horn, one to the other, neither of them could hear any other but harsh and hostile words. And when Llevelys saw this and that there was a demon thwarting them and disturbing through this horn, he caused wine to be put therein to wash it. And through the virtue of the wine the demon was driven out of the horn. And when their discourse was unobstructed, Llevelys told his brother that he would give him some insects whereof he should keep some to breed, lest by chance the like affliction might come a second time. And other of these insects he should take and bruise in water. And he assured him that he would have power to destroy the race of Coranians. That is to say, that when he came home to his kingdom he should call together all the people both of his own race and of the race of the Coranians for a conference, as though with the intent of making peace between them; and that when they were all together, he should take this charmed water, and cast it over all alike. And he assured him that the water would poison the race of the Coranians, but that it would not slay or harm those of his own race. "And the second plague," said he, "that is in thy dominion, behold it is a dragon. And another dragon of foreign race is fighting with it, and striving to overcome it. And therefore does your dragon make a fearful outcry. And on this wise mayest thou come to know this. After thou hast returned home, cause the island to be measured in its length and breadth, and in the place where thou dost find the exact central point, there cause a pit to be dug, and cause a cauldron full of the best mead that can be made to be put in the pit with a covering of satin over the face of the cauldron. And then in thine own person do thou remain there watching, and thou wilt see the dragons fighting in the form of terrific animals. And at length they will take the form of dragons in the air. And last of all, after wearying themselves with fierce and furious fighting, they will fall in the form of two pigs upon the covering, and they will sink in and the covering with them, and they will draw it down to the very bottom of the cauldron. And they will drink up the whole of the mead; and after that they will sleep. Thereupon do thou immediately fold the covering round them, and bury them in a kistvaen, in the strongest place thou hast in thy dominions, and hide them in the earth. And as long as they shall bide in that strong place, no plague shall come to the island of Britain from elsewhere.
