March 15th - the Battle of the Pelennor. In my private arc, it is a day that celebrates the heroism of those who refused to blindly follow orders. For Pippin, for Beregond - my thoughts are with you today, as are North's. North, in spite of her own story, thinks of March 15th only as The Day The Captain Did Not Die.
I wanted to write, but I am still not feeling well enough to do that reliably, so I can only offer a link to Breaking Strain.
