Trying to catch up with everything I've missed in the last few months, and I discovered that I never posted here about the ECT prequel being finished. It's very Royai; it's basically about Roy, Riza, and Hughes during the war in Ishval and how they developed the relationships they maintained for the rest of the series. And yes, a certain scene involving dog tags is included, so those of you who loved that bit in "Brilliancy" can see how it went down.
The prequel is called "Triumvirate" and the link is in my signature. I hope those of you who have enjoyed the rest of the trilogy will enjoy this part too! Thanks for all the support of the stories!
