A while ago I wanted to design a Sword for my Warlock Guardian Hazel-7. Whilst I haven't finished the concept yet (haha) I did want to illustrate it. Kinda the wrong way around but here we are :)
Hazel-7, wielding a sword forged out of the crystals growing around a never healing wound on his chest. Crystals made out of crystalized Darkness & Light. I have some story laying around for that... somewhere.
