My friend Joe plays drums in a power metal band called Artorias, named after an enemy in Dark Souls (fantasy hack 'n' slash game). They asked me to make a logo inspired by the dark fantasy world their songs would sing about.
I sketched some weapons and skulls in my notebook for a bit and sent a first pass of vectors to Joe. I asked for a gut check - which direction (if any) were they leaning. The decision was unanimous, SWORD! I customized the lettering a bit, added some erosion, and of course made the sword bigger.
