The Princesses of Grand Chase was a retention campaign to reward certain outstanding players who compete in, among other things, a battle to the death. In-game, of course!
I fleshed out these designs for a set of the actual rewards for the different categories in the competition; these designs were made into in-game signboards (like digital trophies) that the winners' characters were able to equip and show off to the rest of the game's populace. Further materials like wallpapers and merch were based off of these.
