Anyway - I usually begin every fantasy RPG with a sort of vague 'template' I have (which usually I later re-model and they end up as my main), and it is predominantly A. mage and B. elf (preferably dark elf). Hence I began playing DAI that way - and I had no idea what I was in for, as I've never played either DA or any other Bioware game and only bought DAI after a couple guildies from Elder Scrolls Online sang praises about it. So I gave it a shot - with my 'tempelate' at first of course, which eventually evolved to my main.
I always have a looser template myself, which is usually a rogue (dual-wield) of whatever race has an interesting story or series of attributes. So, all of my DA canons are stabby rogue ladies. I establish a foundation when I start, name, some personality traits and values, infuse the provided backstory with some of my own, and then add to who this person is over the course of playing. I take my time on my first playthrough and go slooooowly, so my first is always my canon.
So I have a Warden who married Alistair, Hawke who ran off with Anders, and now this Dalish Inquisitor who, by the end, has had a lot of things to question. They are all pro-mage freedom though (based on somewhat different reasons). I'm pleased with them all in their own ways.
Though, speaking of Elder Scrolls Online, I started off as Dunmer Nightblade but my boyfriend decided to take a 'break' so I moved to a side character (since we had dark elf rogues for each other) and now I play my Altmer sorcerer most often. Which is weird since I'm generally rogue about 90% of the time and mage 10% and never warrior unless forced to be.
