San Ilia is a location within the Natalia region. The kingdom holds high respect for Ilias, having being named after the goddess.
Defeating a Lamia along the way, Luka signs in to meet the San Ilia King whom will guide him through his journey. Having met Ilias in a dream who informed the king he would meet an unbaptized boy named Luka, the San Ilia King welcomes him and trials him to meet three wise sages and complete their task to obtain the Goddess Sword. Alice steps in and calls it blasphemy as she shatters the sword, sending the king into a delusional state, and tells Luka to find the Four Spirits instead.
Having heard the “Monster Lord” attacking, the guard increases its security.
Just then Granberia shows up and challenges Luka, who repels her after showing off his new techniques.
Luka and Alice head to the library to find the book Four Animists and their Sources to locate the Four Spirits, however a book monster Page 17 pops out claiming that the Monster Lord has forbidden anyone from reading it. As Alice cooks up a few potatoes, she remembers that she ordered three book monsters to protect the book and prevent anyone from misusing the power of the Four Spirits, but does not indulge details. Luka then defeats and Page 257, but struggles with Page 65537, revealing that she is immune to sealing and is only weak to fire. Just then, Alice accidentally sets the place on fire which seals the monster. The guards then enter, having heard the Monster Lord (speaking honestly), Granberia (a lie), or Luka’s idiocy (play dumb) and immediately tries to put out the fire. Alice had manage to take the book out of the building.
Within town, Luka acquires Sacred Anti-Ghost Water and hears a request coming from Port Natalia as well as various rumors from the citizens surrounding a Haunted Mansion. Additionally, Amira reveals that Sylph, whom is in the Natalia region, lies within the Forest of Spirits.
After clearing the Haunted Mansion, the ghosts there begin invading San Ilia and treats it as a haven for them. Additionally, after Luka defeats the Chimera Dryad within the Forest of Spirits, the Fairies invade San Ilia and beings playing pranks on the citizens. As he sets off for the Safina region, Luka wonders if everything will be okay with undead souls and monsters invading a religious place.
Note that San Ilia is an allusion to the real life centre of Catholic faith; The Vatican.
