Since this verse is getting to be a bit of A Thing, I figure I might as well list it all in one place.
In regards to the whole series -
Warnings: Adult having sex with a teenager. The teenager is above the age of consent in the UK, where this is set.
Pairings: Primarily Merlin/Arthur. There's also on-going Gwen/Morgana, past Gwen/Merlin, and discussion of past Arthur/Gwen/Lancelot/Merlin/Morgana and assorted combinations therein.
Summary: Modern reincarnation. Merlin and company have been reborn countless times; this is the story of the latest.
Notes: The 'present' in this is actually a few years in our future. Arthur and Merlin meet at the very end of 2014, and Mere Mortals brings us into autumn 2016.
Prequel:
The Universal Language, NC-17, ~14300 words. In which Morgana remembers her history, and seeks some manner of reconciliation with her present. This piece is focused on Morgana and her relationship with Gwen, and ends a few years before the rest begins.
The main storyline:
All In the Timing, NC-17, ~5600 words. Merlin and company have been reborn over and over, but things aren't quite the same this time around.
Sure Thing, NC-17, ~9700 words. In which Arthur's a teenager and Merlin's not, Morgana's inappropriate, Gwen's a saint except when she's not, and Uther's shady.
Ancient History, PG-13, ~5400 words. In which there are memories of lives past and complications in lives present.
Mere Mortals, NC-17, ~11300 words. In which the past is considered and the future is approached. Meanwhile, Morgana continues to be inappropriate and Uther continues to be shady.
Supplementary pieces:
A Singular Kinda Guy, NC-17, ~3800 words. Wherein Arthur Riley grows up and meets a man named Merlin. A retelling of All in the Timing and the first part of Sure Thing from Arthur's perspective.
In case anyone's wondering - yes, the titles are all nicked from David Ives, no, the stories don't have anything to do with the plays of the same name. I'm just rubbish at titles and it's a handy device. ;)
