Lomasha

Indra explained to the sage that Arjuna shared the throne with him due to the virtue of being his son, and described the circumstances of the prince's birth and identity.

[4] Hearing Yudhishthira's grievances about the success of his unrighteous foes, Lomasha preached to the prince regarding the nature of dharma.

[6] He accompanied them during their visits to a number of holy sites such as the Naimisha forest, Gaya, and the river Yamuna, and explained their significance to them.

[8][9] In the Padma Purana, the legend of Lomasha coming across five maidens of the gandharva race who had fallen in love with the son of a sage is described by Narada.

The young man rejected their advances, and when they attempted to claim him by force, he turned them into pishachas, and they responded in kind.
