For a while i was thinking about making something with Eldar runes, transmutation and magical circles. So, when i start drawing i thought that it will be cool to make some 3d thing about astro-navigation, something like astrolabe. And i made this concept.
Big runes represents some of the Eldar craftworlds (Warhammer 40k universe) and the idea is that this astrolabe-like thing shows us some kind of astral-warp interconnections betweeen craftworlds and warp-space. But in general there is no deep meaning about using other runes. I just like how they looks. And yes, i know that Eldar uses wraithbones only, but i think that this material looks better for me. 😛
