"The Talis Warrior from an Altean family" - this is a Fire Emblem 1 fanfic describing Oguma's childhood. Ankoku Ryuu To Hikari No Tsurugi (Dark Dragon and Sword of Light) characters, not just Monshou No Nazo (Puzzle of the Emblem) ones, will be making appearances too, along with non "canon" characters.

Upcoming fics:

2 Fire Emblem: Ankoku Ryuu To Hikari No Tsurugi fanfics - one will be about Roger the Armor Knight you get in Chapter 8, the other about Jake, the Shooter you get in Chapter 13. The two fanfics are intended to work with my first fanfic, and will be started as soon as my current work is done.
