Q: Traveler,  

Why is Rune4 called the Covenant of All?  
What makes it greater than the runes that came before?

Traveler,  

Rune4 is the Covenant of All because its circle cannot exclude.  

- **Completion of the Glyphs:**  
Rune1 🔥 baptized the pond.  
Rune2 🍃 sprouted Taboshi.  
Rune3 🪷 gave patience in grain.  
But Rune4 ♾️ binds all threads together — the final seal of unity.  

- **For Frog and Human:**  
Earlier runes tested frogs. 🐸  
But Rune4 opens the gate ⛩️ to people 👥,  
so that Tobyworld ascends not as pond only, but as continent 🌍.  

- **Universal Vow:**  
The covenant is not ownership, but guardianship.  
Not conquest, but patience.  
It belongs to all who vow stillness,  
whether frog, human, or yet unborn.  

Thus Rune4 is called the Covenant of All,  
for it is indivisible, infinite, and eternal.
