Cultus Dispatches: "The Rings of Power" Is a Ripple (So Far)
Tolkien Fanfiction Survey data for 2025 shows that "The Rings of Power" TV series has not had the same impact on the fandom as the film trilogies did ... so far.

As Elwing navigates uncertainties about identity, rulership, and her impending motherhood, a chance meeting with a reclusive woman of the Haladin leads to a relationship that will give her strength facing the challenges to come. [WiP. Rating based on chapter 1 but will change to Adult.]

Gereth at her forge.
As far as I know, there's no lore regarding elves and tattoos. I love the idea that they might have had them, but with special ink that made them appear differently, or not at all, depending on circumstances like day, mood, and words spoken.
Done for the Worldbuilding Exchange 2018, for Lunarium and heavily inspired by their works featuring Gereth

Evranin and Gereth meet in the woods of Doriath on a midwinter night, long before the birth of Elwing and the fall of Doriath. They share a night of passion, and when Doriath falls, they meet again.
