Amandil, a few years before the Invasion of Valinor, sneaked off the island with three of his most trusted men and attempted to sail to Valinor to ask pardon and forgiveness for Númenor. He was never heard from again, though it is possible that the Valar heeded his plea considering the faithful were spared and their ships were pushed to safety from the Destruction of Númenor.
Would the Valar have spared the faithful if Amandil had not attempted to sail to Valinor and beg them for forgiveness?
