There are a lot of natural disasters that happen around the world every year, including earthquakes. I was born in a country that experiences a lot of earthquakes: Taiwan. There are around 2000 earthquakes per year, and strong earthquakes occur quite often as well. As a result, we have a legend about the earthquake.
There are also a lot of earthquake legends related to animals in other countries, such as Japan, Chile, Mongolia and Siberia.
These legends are what inspired me to create this series.
