Elrond/Haldir plotbunny by Kira Romashko
Haldir is sent to Rivendell to protect Elrond, but Elrond won't listen to anyone, and goes away to, let's say, Dol-Guldur, to fight himself. And Haldir has to stay by his side. Please, no 'poor Haldir wounded and dying and Elrond saving his life.' R or NC-17.
