After a rift is repaired, Tri finds two more large rifts, where you can go to look for the other missing people.
Read Lueburry's Diary
After you learn about the two rifts, you can first go downstairs and read Lueburry's diary.
Talk to Lueburry
Talk to Lueburry to learn that the five unusual crystals that you got after defeating the Seismic Talus are also known as Might Crystals. After you talk to Lueburry about it, you can check on the machine in the corner to enhance the Sword of Might, or to increase how much swordfighter energy you can hold.
Talk to Lefte
You can optionally talk to Minister Lefte to learn more about the areas near the rifts.
Add a Waypoint
When you're ready, go outside. Start by going west. Check on the waypoint to add it to your map. Go north, and you can optionally read the sign that has a drawing of you on it.
Visit Suthorn Village
You can optionally warp to the waypoint east of Suthorn Village and visit the shop, where you can now purchase Blue Potion, which restores swordfighter energy, and Purple Potion, which restores both swordfighter energy and hearts.
While in the village, you can also talk to the person in front of the southwest house to start the sidequest Finding the Flying Plant.
When you're ready to continue, warp back to the waypoint to the north, go northwest from the waypoint, then go north. You'll be in a southern part of Suthorn Prairie.
Southern Suthorn Prairie
You can learn new echoes here, such as the Crawltula echo and the Octorok echo. You can bind to Octoroks and pull them out of the water to make them easier to fight.
In the northeast part of the area, you can start the side quest Up a Wall.
Northwest of Lueburry's house, you can talk to someone to start the quest The Blocked Road. Complete it, then go north through the opening that you created, then go to the waypoint to add it to your map. From there, go west along the dirt road. Keep following the dirt road until you reach another sign. Go west from there and check on the waypoint, then go north and check on the stone pedestal to meet the Stamp Guy. Check Stamp Stand Locations to see where to find more Stamp Stands. Then go north into Hyrule Ranch. You can go into the building to buy Fresh Milk. Then talk to the man west of the building to start the quest Runaway Horse. After that, you can borrow any horse from the ranch for free, but not the white one.
