Story inspired by this:
"The fëa ... is summoned; and the summons ... is imperative; yet it may be refused."
Morgoth's Ring, The Later Quenta Silmarillion, On Rebirth...
So, the Valar cannot force Elves to chose the right path.
"Indeed the refusal of the summons is in itself a sign of taint."
This interpretation is from the POV of the Noldor; I'm suggesting the Silvans might have seen things differently.
In my stories, I use the word Tawarwaith* about the followers of Nimrodel, those who believe in the old ways. They don't trust the Noldor; they are strongly connected to their wood; and they are somewhat suspicious of the Valar.
It was pointed out to me by my friends from GoI that Námo/Mandos' proper Sindarin name is Bannoth, however, I still chose to stick with the - to me - more familiar Quenya terms.
'Sadron' is used as a respectful title among my Tawarwaith; it means 'Faithful one'.
*) Tawarwaith simply means 'Forest People' and is a term used about Wood-elves.
