What if they become a fifth playable race?
What if they become companions?
What if they're... *Gulp* romanceable?
If a drawing on a rock becomes an LI for DA 4, then I'm gonna flood BW's office with demands to make other characters - including NPCs - to become companions and fully romanceable as well.
Just to name a few: Varric, Nathaniel Howe, Cole, Sigrun, Lace Harding, Aveline, Knight-Templar Barris, Duncan, Bann Teagan, Gorim, Shianni, Flemeth, the Arishok from DA 2, Sten, Loghain, Gaspard de Chalons, Abelas, Knight-Commander Greagoir, Ser Jory, Mother Gisele, Michel de Chevin, Oghren, Lord Abernache, Samson, Inquisitor Ameridan (in the Fade, warp through time, whatever, don't really care), the whole members of Red Jenny, Arishok Sten, Vivienne, Mark Darrah, Soris, the Nightmare demon, Bianca Davri, the Mother, the Architect, the Lost, the Disciple, Ser Varnell, Mother Petrice, David Gaider, Ser Pounce-a-Lot, the Hawke siblings, Rendon Howe, Herren and Wade, the Blighted werewolf, the guardian at the Gauntlet, Andraste's ashes, Shale, King Cailan, Justice, Envy, Mouse, Seneschal Varel, Bann Esmerelle, the Archdemon (all 5 of them), Genevieve, Bregan, Maric, Janeka, Utha, the Viddasala...
...and many others who shall not be forgotten.
