Follow the rock edge → inspect the newly exposed side alcove → enter → interact with the cyan glow.
Checkpoint 3 station, facing the normal route toward Checkpoint 4.
Checkpoint 3 unlocked and enough water removed to expose the side alcove.
The relic interaction completes and the Mysterious Relic badge popup appears.
Find the exposed rock alcove
Unlock Checkpoint 3, then continue draining the water around the route toward the next station.
Stay against the grey rock edge and look for a small side opening that becomes reachable as the water drops; do not continue all the way to Checkpoint 4.
Enter the alcove and approach the bright cyan object at the back.
Use the interaction prompt and wait for the Mysterious Relic badge popup before leaving.
Use the glow, not a distance estimate
The reliable landmark is the concentrated cyan glow inside a shallow grey-rock alcove. Camera distance and water height change as the lake drains, so a fixed number of steps from the station is less reliable than the opening and glow.
If the alcove or award is missing
If the opening is still underwater, keep draining the local section and return to the Checkpoint 3 rock edge.
If you reached Checkpoint 4 without seeing it, walk back along the same rock wall; the relic is in a side alcove before that checkpoint.
If the relic is visible but has no prompt, approach the cyan object from inside the alcove and move the camera off the wall.
If the prompt completes without a popup, check your Roblox badge list after rejoining once before repeating the route.
