Some of my favorite things about Drowtales:
1) At the time, the most attention I'd ever seen to the artwork in a webcomic. A full - color, fully immersive world. Since then, I've discovered others that are comparable, but not better, and none of those update more than twice a week.
2) The story, like the art, is fully immersive. I fell in love with the main characters from the first page I saw: Ariel, the confused child who has no idea about the truth of who her family really are. Syphile, the worst babysitter in the history of fiction - and yet a tragic heroine in her own right. And so many, many others. It's the story of many people, and it maintains the illusion that any random nameless character could become the protagonist of the next story arc. These people are fantasy monsters, and yet they are just as human as, well, humans. And not in just a comedic parody of fantasy, either, but in a realistic way.
3) The world of the clans, each with their own culture, architecture, etc.
