When Prince Guru Gantangan was a teenager, the King married Nyimas Padmawati, a princess from Sunda Kingdom.
From Queen Nyimas Padmawati, King Silihwangi had a son called Prince Mundinglaya.
This decision made the people and the nobility in Pajajaran took sides and the discord threatened the kingdom to lapse into a quarrel among brothers.
One night Queen Nyimas Padmawati, Prince Mundinglaya"s mother had a strange dream.
The Queen heard the one who was holding the amulet in his hand, saying to the others: "There will be peace in Pajajaran only if a knight dares to fetch it from Jabaning Langit".
The king was very interested in the dream and immediately asked all the people as well as the nobility, including Prince Guru Gantangan and Prince Sunten Jaya to gather in front of the palace yard, where he told them about the queen's dream.
He was afraid of facing Jonggrang Kalapitung, a dangerous, forbidding giant who watched over the road.
After a moment of silence it was Lengser, the Prime Minister, who raised his voice: "Your Majesty," he said, "everybody has heard you speaking, but there is still one man who has not.
Since Layang Salaka Domas is important for the security of Pajajaran, I am willing to go, Father," said Prince Mundinglaya.
Several weeks, Prince Mundinglaya was taught martial arts and how to use weaponry as a preparation to combat obstacles hindering his way to Jabaning Langit.
Leaving it to the guidance of God, he walked through thick forest to find Jabaning Langit and meet guriangs.
Prince Mundinglaya promised to meet her again after he has finished his duty to have Layang Salaka Domas.
Thinking that he was betrayed, Prince Mundinglaya pressed the creese deeper into the giant's neck.
Then the Prince let the giant loose, saying: "I let you free, but do not trouble the people from Pajajaran any longer."
When he was gone, Prince Mundinglaya found out a place for meditation, prayed very long, asking God for advice.
There he was received by seven "guriangs" (supernatural creatures), one of whom was holding Layang Salaka Domas.
"My purpose is to fetch the Layang Salaka Domas needed for my country as a remedy for a quarrel between brothers.
Immediately another magical creature, Nyi Pohaci appeared at the place where the "guriangs" were standing around Prince Mundinglaya's lifeless body.
Then he left for Pajajaran escorted by the seven "guriangs" who then called themselves as one group: Gumarang tunggal.
To the king he said that Queen Nyimas Padmawati did not really dream, that she had lied to free her son from prison.
