The peaceful Iliasville, where Luka starts his journey in Paradox. At such, characters have a lot of information to share that could be useful for a beginner adventurer. There's also a lot of equipment to get left and right.
After having saved Hans the lumberjack from the Bunny Slime, Luka has to go to Ilias Temple to get baptized, and comes back very soon as an angel and a monster are fighting. After chosing one, Luka has the option to visit the village's chief to get additional supplies. He can also save a slime girl stuck in a poisonous swamp west in the town, and give a final good bye to Aunt Betty, Lazarus, and the other villagers.
It is possible to ignore all that and rush on the road as soon as the main heroine is recruited. Doing so will radically change the game, as Luka won't be able to recruit the random monsters he encounter, only the ones fixed in the story.
