inal answer:
Merlin tells Uther that it will cost him to have Ingraine, referring to the future child who will bring both prosperity and tragedy to the kingdom.
Step-by-step explanation:
In the story of Merlin and Uther, Merlin tells Uther it will cost him to have Ingraine. The cost that Merlin refers to is the future child that Uther and Ingraine will conceive together. Merlin predicts that this child, who will later become King Arthur, will bring both great prosperity and great tragedy to the kingdom.
This is a key moment in the Arthurian legend as it sets in motion the events that will lead to the birth of King Arthur and the establishment of the Knights of the Round Table.
Merlin's prophecy highlights the complex relationship between fate and free will, as Uther must weigh the potential cost of his actions against the potential benefits for his kingdom.
