Here's a sword design I made for one of the summer events in RuneScape this year. I wanted to get across the idea of a sort of evil force trapped within the blade, so I played around with a lot of interesting hue shifts for the metals. I asked if there could also be a voice-over of the sword whispering things to the player as it was worn, but I don't think that made it in-game sadly :D
