Mysterious Force Blox Fruits: Temple of Time

The Mysterious Force is a bodiless NPC that arrived with Update 17.3, serving as a gateway to the Temple of Time. You find it at the summit of the Great Tree (Third Sea), and a second time inside the Temple of Time to make the return journey. Interacting with it tears the space and teleports you. It's part of the King Red Head quest chain, the step that leads to the resonance of your Race.

How to get it

At the summit of the Great Tree (Third Sea), and inside the Temple of Time for the return.

The Complete Walkthrough

Step 1. You talk to the King Red Head, who sends you to the Great Tree.
Step 2. You climb to the top of the tree: the Mysterious Force awaits you there.
Step 3. You interact with it, it teleports you into the Temple of Time.
Step 4. Once there, you must find the Mysterious Force a second time and choose "use it".
Step 5. You return to see the King Red Head, who explains that your power only works during a full moon.

This last constraint has been removed: since Update 19, using your Race ability no longer requires a full moon.

Dialogues Outside (Great Tree)

Message	What it means
There's something there, but you can't quite place it.	You haven't yet beaten rip_indra, so you haven't yet spoken to the Sealed King. Access is closed.
You feel a force here...A remnant of the past. Then the message: The space tears open, and you arrive in a new place.	You have access: the force opens and teleports you.
This place has an ancient feel. Perhaps you should return to the Sealed King.	Displays just after the previous message, the very first time you enter.
A strong force prevents you from entering. Come back later.	Other players are occupying the trials. You'll be able to enter when they're done.

Dialogue Inside (Temple of Time)

Message	What it means
You feel a force here...	If you choose "use it", you are immediately teleported outside.

It's your exit: the same force serves as both way and return.

Inside the Temple of Time, where the same force serves as the exit.

Good to Know

The Mysterious Force has no character model: there's literally nothing to see on screen. It shares this with the Weird Machine and the Sealed King.
Access is shared between players: as long as someone is in the trials, the door remains blocked for you.
The real prerequisite is having beaten rip_indra, since that's what triggers the interaction with the Sealed King.
It arrived with Update 17.3.

Note: the source is uncertain about the name of the NPC who sends you there: the page's walkthrough mentions the King Red Head, while the dialogues refer to the Sealed King. Fandom doesn't settle this; we provide both names as they appear.
