It's actually quite simple!

Leon's Japanese name was written with the characters "ri" & "o" & "n"

"Ri" can also be translated as "Li"

In English, it's the word "lion" even though the romanji is pronounced "Leon"

Lots of early Tales of Destiny sites that were written after the Japanese game release called Leon "Lion"

Hence, I chose to call this site "Shrine to the Black Lion"

Make Sense?
