1.Anders, Zavern, Lilianna are Andrastians and they are bi. The Divine current is into girls.
2. That's the only time of transgender the game can get. This is a world in post-midevil times.
3. And the male LI is "unconventionally attractive"? Men would kill to be half as attractive as the male li in the games.
I probably shouldn't be doing this, but...
1. First I said most, and even if I hadn't, the fact that exceptions to a trope exist do not disprove the trope. That's like saying the straight white male gamer doesn't exist as a trope, because there are other types of gamers. Patently false. As the the Divine, she was a former bard, so we have no idea if her thing with Marjolaine was 'business related' or true attraction. That's been brought up several times now, and the answer remains, we have no idea what her sexuality is. It, like with most bards, remains ambiguous.
2. Transgender=/=drag no matter what world you live in. Drag is a type of performance, often a bit over exaggerated. Being transgender is being born in the wrong body. Transgenders are not 'cross-dressing' really, and it is never a performance. And telling us Serendipity was trans felt like a joke, the over-affectations, the remarkably deep voice and overdressing are heralds of being a drag queen not a trans woman. I feel like this needs to be said again so, a transwoman is just a woman, a drag queen is an over-stylized portrayal of a woman. Not the same thing. This doesn't change no matter when you are (though Dragon Age resides in its own separate universe, not really our 'post medieval' era.)
3. Point of taste, many people have brought this up on the forums, so I brought it up here. For reference, lithe and petite is what is considered 'conventionally attractive' as in every female LI ever. If Aveline had been an LI, this wouldn't be a thing as much.
