Female Avatar (Fire Emblem: The Blazing Blade)

This was an informal request.

From the Fire Emblem Wiki

Mark is an enigmatic person whose true name, personality, and birth date (and blood type in the Japanese version) is determined and interpreted by the player. While their entire history is unknown prior to the Prologue, Mark is an aspiring tactician wandering all of Lycia to improve their skills. They occasionally appear on battle map preparations for dialogue and several characters talk to Mark in chapter cutscene dialogue and in some rare instances, can be seen obscured from behind in some CGs. Lyn, Eliwood, and Hector in particular have special sprites that have them looking at Mark during discussions with them. However, Mark has no in-game dialogue and it is left to the player to determine what they say based off the other character's prompts.

In short, Mark is the default name for the player avatar in Fire Emblem: The Blazing Blade(or just Fire Emblem if you are are a US fan), and this is a female version based largely on the artwork of zunbayasi. There's not a ton of good art for this so don't expect too much but it seems to largely work.
