Only a remnant of the Faithful could be saved when Elendil and his sons managed to escape Numenor.

Brief history:

The Faithful were the minority of the Numenoreans who remained friendly with the Eldar and obedient to the Valar, despite their fear of Death and the Doom of Men. The Faithful arose about SA 2300 and founded Pelargir in 2350 as their chief haven in Middle-earth. They continued to sail to the northern coasts of Middle-earth and aid Gil-galad against Sauron. Beginning with the accession of Ar-Gimilzor c. 3100, the Faithful were actively persecuted, being punished for speaking Eldarin or meeting with the Eladar of Tol Eressea. The Faithful were forced to move from western Numenor to the east, where Romenna became their chief city; many emigrated to Lindon. During the captivity of Sauron in Numenor (3263 - 3319) the Faithful, now led by Amandil, Lord of Andunie, were bitterly oppressed, and some were burned as sacrifices to Melkor in the Temple built by Sauron. Yet in the end a remnant of the Faithful survived the downfall of Numenor and, led by Elendil, Isildur, and Anarion, founded the kingdoms of Arnor and Gondor in Middle-earth.
