[X] The Men of Sunlight
This has has some excellent contrast with the immediate consequences of Doom, Unerring as they were once Men of Twilight captured, and taken into bondage only to be rescued by a grim faced ranger who they followed into a wondrous city under the star. This means despite their short lives compared to the sons, and daughters of Numenor they will me making the most of the time that is given to them while being a rather joyous people who've been rescued from torment to live free under sunlight.
Meanwhile their cousins from Numenor are likely to be rather grim faced as they will not even have traditions that many in their heart of hearts adhere to in the hope that doing so will
someday grant them the gift of immortality, and morale will suffer even with what counsel Elrond gives, but I think it will pass as all things do in time especially under these circumstances. Because they have been given through no action of their own a lifespan that allows them to see generations of their cousins live, and wear down their sense of entitlement that the blessings passed onto them for the deeds of their forefathers has given them.
[X] Doom, Unerring
I've already done a
post already on my initial thoughts on the options, and in addition them I'd like to note that this option seems like it has potential to better connection with the Middle-Men as they never had messengers like the Faithful sent to them. That being said we'll likely want to take some of the other options in the future depending on how things work out.
Also this seems likely to result in a people more focused on deciding what to do with the time that is given to them, and that should serve for an interesting contrast to Numenor proper.
[X] Plan Green Shoots of Hope
While the delay in construction won't look particularly good with the Shaper representative showing up after some contemplation... I suspect without doing it Hazraban is unlikely* to venture so far away from the walls of his tower, and journey to Rivendale. This is an issue as without that I suspect his people will continue down a path all too similar to the Black Numenoreans, and it would be all too easy for a group defined by being good soldiers to be put to ill use in the region by Sauron once he gains influence in the blessed isle.
That being said it is entirely possible for Hazraban to be healed only for his descendants to fall back into darkness, and Tharbad to become a route for evil to foster darkness in the hearts of those who dwell within the region again, but it is worth a shot to plug this particular hole imo.
*This isn't at all surprising as MoS indicates the hatred runs deep.
