If the naming convention wasn’t a hint, this is based off of the general look of the Totem of Undying. However, I hue shifted the normal palette to fit the color scheme of the Guardian. For the spikes and fin though, I used the original Totem palette. Also, instead of emerald eyes, I changed it to red, which could either be interpreted as redstone or ruby. Also also, the “keeping” part of the name might be a little confusing, but “to keep” is to maintain or take care of, and I see it as the Idols of Keeping being built to maintain the Ocean Monuments after they’ve gone to ruin, or were built before their ruin so they could prevent them from dilapidating.
