 Background Knowledge
The Lost Cathedral is where the final battles take place in Tales of Souls Mode. It is said to contain all of the major types of influential architecture across Europe. Its location is untirely unknown, and it is said that it can only be found by those who are strong and willing enough to bet their own lives in battle. Nightmare and Siegfried have their final showdown here, and once you are able to defeat them, you must defeat Abyss.
