"The one aspect of this request I was unfamiliar with was Kingdom Hearts. As far as I understood it, there was only one Keyblade. Yeah, that's how clueless I was. Luckily, my husband helped me understand the lore. So for the main blade component, I am using the design of Fierce Deity's sword. Any Zelda fan will recognize this iconic blade at first glance. Obviously, the key component will utilize the design of Majora's mask, altering its spikes into key pegs, similar to how the final battle occurs when it grows appendages. Of course, the moon will be the charm attached to the chain. The toughest part to figure out for the design was the hilt of the sword. I originally wanted to incorporate the Deku, Zora, and Goron masks, but I couldn't figure that out. Instead, I used Rauru, the owl, and some directional buttons for playing the ocarina as the hilt."
