This could be the right place to ask.
Do we have any idea what the original creators imagined that the Rogue-invented monsters look like?
I mean the Aquator, Emu, Ice Monster, Kestrel, Quagga, and Xeroc?
I know the Kestrel is a real bird, and the Quagga is a real kind of horse, but I wonder whether they visualized it as an especially monstrous version... and the same goes for the Emu btw. But I'm of course wondering most about the Aquator, Ice Monster, and Xeroc...
Do there exist screenshots of these from the first graphical version of Rogue?
