Widdershins by Kate Ashwin explores several interlinked tales set in a city where magic exists cheek-by-jowl with myriad other legal and illegal ways of making a living. Harriet Barber and her magic-detecting dog are on the case, along with half a dozen other engaging characters.
Al'Rashad by Chris "Mightygodking" Bird and Davinder Brar is the slightly more serious saga of what happens when the heir to a Northern kingdom becomes lost in a huge, sprawling quasi-Middle-Eastern city with its own seriously entangled politics. Swashes are buckled, witticisms are exchanged and an intriguing world is gradually revealed to the reader.
There's also some quality worldbuilding going on in Der-Shing Helmer's The Meek. Three different peoples are forced to share too little land-- could the strange green-haired girl be the key to everyone's salvation? She's off climbing trees naked, so who knows. (There is nudity in this story, but it's amusing cartoon nudity rather than exploitative nudity. Nevertheless, your boss might not catch the distinction, so NSFW.)
O Human Star by Blue Delliquanti is a beautiful, beautiful thing. Our protagonist awakens one day, surprised because the last thing he remembers is his own death. He finds that his body is now artificial and identical to his former, organic one. Now to find the love of his life, with whom he did such pioneering work in robotics all those years ago...
Where O Human Star is romantic and futuristic, Chester 5000 XYV is retro and splendidly pornographic. NSFW, obviously. Drawn with decorative Art Nouveau splendour, this wordless comic effortlessly conveys humour, drama, genius and a truly vast amount of robot sex.
Speaking of sex, if you're not religiously reading Oglaf, you're missing out. And by "religiously" I mean ON YOUR KNEES, COMICS SLAVE.
Till next time, true believers!
