Gronw Pebyr pursued the stag, and by the River Cynvael he overtook the stag, and killed it. And what with flaying the stag, and baiting his dogs, he was there until the night began to close in upon him. And as the day departed and the night drew near, he came to the gate of the court. "Verily," said Blodeuwedd, "the chieftain will speak ill of us if we let him at this hour depart to another land without inviting him in."
"Yes, truly, lady," said they, "it will be most fitting to invite him."
Then went messengers to meet him, and bid him in. And he accepted her bidding gladly, and came to the court; and Blodeuwedd went to meet him and greeted him, and bade him welcome. "Lady," said he, "Heaven repay thee thy kindness."
[Now Blodeuwedd, in spite of her descent from the flowers, was at heart a wicked woman, and so she began to plot with Gronw Pebyr how they might slay the valiant Llew Llaw Gyffes, and enjoy his possessions. Then Gronw said to her,] "Converse with him fully, and find out by what means he may come to his death."
That night Llew Llaw Gyffes returned to his home. And the day they spent in discourse and minstrelsy and feasting. And at night they went to rest, and he spoke to Blodeuwedd once, and he spoke to her a second time. But for all this he could not get from her one word. "What aileth thee?" said he. "Art thou well?"
"I was thinking," said she, "of that which thou didst never think of concerning me; for I was sorrowful as to thy death, lest thou shouldst go sooner than I."
"Heaven reward thy care for me," said he. "But until Heaven take me I shall not easily be slain."
"For the sake of heaven, and for mine, show me how thou mightest be slain. My memory in guarding is better than thine."
"I will tell thee gladly," said he. "Not easily can I be slain, except by a wound. And the spear wherewith I am struck must be a year in the forming. And nothing must be done towards it, except during the sacrifice on Sundays."
"Is this certain?" asked she.
