There the son of Maharaja Uttanapada, the great devotee Maharaja Dhruva, still resides as the life source of all the living entities who live until the end of the creation.

SB 5.23.1, Translation

Śukadeva Gosvāmī continued: My dear King, 1,300,000 yojanas [10,400,000 miles] above the planets of the seven sages is the place that learned scholars describe as the abode of Lord Viṣṇu. There the son of Mahārāja Uttānapāda, the great devotee Mahārāja Dhruva, still resides as the life source of all the living entities who live until the end of the creation. Agni, Indra, Prajāpati, Kaśyapa and Dharma all assemble there to offer him honor and respectful obeisances. They circumambulate him with their right sides toward him. I have already described the glorious activities of Mahārāja Dhruva [in the Fourth Canto of Śrīmad-Bhāgavatam].
