Guan returned to the surviving humans. He spoke to them via telepathy (for his mouth was sewn).
"The Ancestor is lonely," Guan projected. "He seeks warmth. That is why he kills us. To stop him, we must give him a home."
"We cannot build a house that won't rot!" the humans cried.
"We will not build a house of stone," Guan said. "We will build a house of Aspects."
Guan gathered the nine strongest leaders of the tribes.
Ignis, who bound Fire.
Terra, who bound Gravity.
Aeros, who bound Storms.
Aqua, who bound Ice.
Ferro, who bound Metal.
Vita, who bound Blood.
Umbra, who bound Shadow.
Psyche, who bound Dreams.
And Guan, who bound Silence.
"We must create a prison," Guan said. "We must become the walls."
