Once I decided to base the ancient, evil creature on the idea of chaos, I did a little research into its symbolism, similar to how I looked at ego. Fortunately, this time I was able to find something usable:
The symbol represents infinite possibilities as I found out: (http://symboldictionary.net/?p=1121) and I find it quite visually appealing. It’s pretty static in its graphic form but I feel I can manipulate it and transform the actual symbol into my monster, rather than just incorporating the symbol into the design.
Initial ideas are leaning towards the idea of the arrows being tentacles, possibly falling inline with lovecraftian horror– this works on an obvious visual similarity to creature like the cthulu but also plays into the themes of the occult and unknowable as I want my ancient evil to be mysterious.
