Just like Prometheus brought the fire of the gods down to humankind, so does this humble glitch sneak out a couple of 'lost' concept art pages from the creators of Ur.* If you want to take a peek into the thoughts of giants before they came alive, check the pics out here:

(*They are not real concept art; no actual confidential Glitch document was involved, so please don't send rooks to feast on my liver, thank you. :-) )
Comments, critiques are welcome, as are any suggestions on creatures to draw next. Cheers! :)
