East Atlasdam Flats
If Cyrus is your first character (and it is, according to this walkthrough), then you will meet someone whenever you reach the end of the bridge that leads to Atlasdam. It appears this person has been injured and wishes for a Healing Grape. Go ahead and give one to him, and the person will introduce himself as Kit, who is on a journey to find his father. This is the first Side Story in the game and no matter which character you choose as your main, you will find Kit outside of their starting city. This Side Story's name is called Kit, the Traveler, and that's all there is to it.
|Helped Kit by giving him a Healing Grape||1,500 Leaves|
Note that there are more people to use Scrutinize on back in Atlasdam, as well as a few Side Stories, but you will be returning there shortly. Back to the main event, there is a chest located not too far southwest from Kit, which contains an Inspiriting Plum. Grab it, then start following the trail going east. This will turn south and you should be able to spot a chest to your south. Continue moving south and take the side path going east to the chest you just saw, which contains 500 Leaves. Continue south and you will arrive at North Rippletide Coast.
North Rippletide Coast
To start, there is a chest not far off to your right, which contains a Fortifying Nut. Keep going south until you hit a save point, where you can either head right and further south. The southern path leads to a dead end with another chest (Healing Grape), while the other way lets you continue. There will be a trail that veers off to the right, leading down to the beach and another chest (Olive of Life) and if you venture on a slightly hidden path north of the chest, you will find Undertow Cove. Unfortunately, this place has a Danger Level of 45, so it's best to avoid it and return to the main path. You'll find yourself approaching East Rippletide Coast.
Note: The Danger Level of a place dictates the level your characters should be at before exploring it.
East Rippletide Coast
Just follow the path to a save point and just below that will be a wooden sign. Read this to see that Rippletide, your current destination, is off to the west. While you can explore to the south, just head west into Rippletide.
