Ti
Ti (pronounced tai or tie)is the dodecahedron as stated first by the male Savant Deedricks who argues against the Dion lexa in the arguing chamber in Meglos Part One, he says,"...and trusted to death no doubt! How can there be any respect for a creed that practices primative sacrifice? Are you making sacrifices now in the name of your monsterious myth?...No this should be said before all Tigella, the dodecahedron is no god!"
Again the dodecahedron is said to be a god by General Draham Mcgregor when he speaks to Meglos, he says,"But what you're asking us to do is impossible...and they guard that dodecahedron with their lives,to them its a god."
Meglos informs us that Ti the dodecahedron was made on Tigella and is an extremely potent power source, which the Dions and Savants are using only at a fraction of its potential. (Its potential is about twelve times that of what it's current output is. Meglos says its equal to all the energy in the Universe.)
Ti, which is, through out the episodes, refered to as she, is both the Dodecahedron and a metaphysical form conjured through beliefs. The blessings of Ti through the Dion Oath show this metaphysical connection to the power that the dodecahedron contains.
