[Saurreg]

From the Silmarillion, I learnt that the hall of mandos was used for housing the fea of the eldar and perhaps the dwarves'

My question is; did Mandos had any jurisdiction over the fate of men? Elven fates are forever tied to Arda and so they die and reborn again, however Illuvatar had given men a gift to depart from Arda thereafter death. I would like to think of it as another plane of existence, paradise if you would.

So if my assumption is correct, than Mandos would have no power over men would he?
