Only have 3 playthroughs set in stone atm: Lin'Mi (female dual-wield Dalish Assassin rogue (her name is elvish for 'blood blade')), Tal-Shok (male 2-hander Qunari Reaver warrior (his name is Qunlat for 'true struggle')) and my Cadash (female archer dwarf Tempest rogue (name undecided atm)).
Personalities:
Lin'Mi: Chaotic Good. Pro-Dalish, pro-elf, pro-mage. Humorous.
Tal-Shok: Chaotic Neutral. Stoic, direct, Pragmatic. Goes with whichever side provides the best assets to the Inquisition.
Cadash: Neutral Good. Fun-loving, humorous, doesn't like politics. Pretty indifferent on most things.
Romances:
Lin'Mi: Solas. Was originally going to go with Sera, but something dragged me towards deciding to romance Solas. No idea what.
Tal-Shok: No one. I seriously can't see him getting along with anyone well enough to form a romance.
Cadash: Iron Bull. Mostly so I can laugh at the height difference.
