Cherub's Gate is a sacred flaming sword which once rested on a pedestal in the center of Celestia City, atop the Astral Tower in the now dead world Terralius. It was the sword used by Rune to strike down Malovus in Judge and Executioner.

Legends say that when the universe is threatened, the sword will draw it's chosen weilder toward it.

The Cherub's Gate can be summoned by it's wielder in his/her darkest hour, using it's flame to "lead it's chosen towards the light".
