Nimbus Fields is the early Breezy Plains grassland most Pathfinders learn first, built for levels 5 through 15. What a lot of players miss is that the region has a second map layer running underneath it, with its own teleport points that never show up while you are looking at the surface map.
Quick answer: There are two underground waypoints below Nimbus Fields. Enter the southern shoreline cave for Sub-Idyllian Ruins, and the northern cave by the Cave Explorer NPC for Crystal Cave. Touch each monument to activate it.
Where the underground waypoints appear on the map
Open the world map while you are in Nimbus Fields and switch the map layer to Crystal Cave – Underground. That toggle is the only way to see the underground teleport icons, the cave corridors, and your own position once you are below ground. Until you activate them, the waypoints sit there as unlit markers, which is a useful way to confirm you are heading to the right chamber before you commit to a long cave run.

| Waypoint | Entrance | Landmark to look for |
|---|---|---|
| Sub-Idyllian Ruins | Southern cave, by the shoreline | Glowing blue roots around the opening |
| Crystal Cave | Northern cave, above Breezy Plains | Stone stairs, campfire, Cave Explorer NPC |
The two caves are not connected by a route you would want to walk. Treat them as separate trips, and unlock the southern one first since it is a short glide from an existing surface teleport.

The Lumin Collection challenge in the same chamber
The Sub-Idyllian Ruins chamber also holds a Lumin Collection time trial. Start it and gather all ten Lumin energy particles scattered across the ruins platforms before the timer runs out. It is worth clearing while you are standing there, since the waypoint you just lit up makes coming back cheap anyway.

Unlock the Crystal Cave waypoint from the northern cave
Leave the track marker active for the whole run. Once you are inside the cave the corridors branch, and the marker is the fastest way to tell which chasm is worth gliding over.
How to confirm both teleports are active
Open the map, switch to the Crystal Cave – Underground layer, and check both markers. An activated waypoint can be selected the same way a surface sanctum can, with a Teleport button appearing once you pick it. If a marker will not let you select it, that monument has not been touched yet and you still need to reach it on foot.
With both monuments lit, the cave network stops being a one-way trip. You can drop straight into the ruins or the crystal chamber from anywhere, which matters for the chests, Lumin Ambers, and Pathfinder challenges scattered under Nimbus Fields that would otherwise mean repeating the entire approach every time.
