How old are each of the main characters in lore?

[Erendis]

@MoofiaBossVal You say it like G'raha had a choice to live on the First after we left. Even when creating crystals for transference he was already heavily damaged by the tower and probably did not expect to live long. And after Elidibus used tower to summon all the shades it was only a matter of hours when G'raha will turn to crystal. So his choices really were:
1. To die on the First and stay dead.
2. To die on the First and try to have a second life on the Source.
