Terra of the Left

Terra of the Left (左方のテッラ) is a member of God's Right Seat. Like the rest of God's Right Seat, his name is derived from the Italian version of his particular element, 'Earth' or Terra, in this case. The antagonist of Vol.14, and ends with his life taken by Acqua of the Back in the same novel. He was also the one that gave Touma a clue about his Imagine Breaker's true power. But before he could say it he was engulfed by flames that erupted from one of Academy City's HsB-02's attack.

Personality
Terra strongly believes that God's Right Seat is more important and has a bigger role in the Catholic Church than the Pope, he openly states that he desires to save absolutely every soul so that they can reach the holy kingdom when the time of the judgment finally comes, but it is later revealed that he sees everyone outside the Roman Catholic doctrine as "not being human" and "not worthy of being saved". He also believes his goals to be absolute and that he is doing what's best for the Lord, and that humanity is not yet ready to be saved and thus requires him to preparate them until they are worthy.

He is fond of long term strategies and complicated plans and has no qualm whatsoever in involving innocents in his schemes as they are simply pieces for him to use, and being used by him will only set them in the path to Heaven whether they live or die in the process.

He was shown to have a great share of knowledge in several aspects, easily pinpointing that Touma was "acting" towards his friends from his own mannerisms and reactions about the subject, as being well versed in several magical subjects; even to the extent of knowing about the Imagine Breaker's true prowess.

Abilities
One of his powers are manipulation of wheat flour, as a symbol of 'Flesh of God' and the Fruits of the Earth, similar to red wine being the 'Blood of God'.

Using his Execution of Light (光の処刑) spell he can change the 'Hierarchy' of things, since something of a higher hierarchy cannot be harmed by a lower hierarchy. For example making a grain of wheat higher than brick walls, so wheat will be able to cut through walls. This particular power is derived from how a Son of God, Jesus, can be impaled by mortal men, as Jesus is of a higher hierarchy and should not be killed that easily. But by changing the hierarchy of things Jesus was able to martyr himself. Though this is mentioned by Terra himself to be a spell designed solely to explain how Jesus is martyred after the fact and most likely wasn't the real cause, as to avoid a paradox that Christianity can't explain. The weak point of this ability is that Terra needs to verbally state which element has it's hierarchy changed and he can only change the atributes of "one element" at the time, the nature of his ability works in the vein of a comparison; for example he can choose air and make it "stronger than steel", as such he needs to understand the object that he is altering, which translates in him being unable to properly affect unknown objects.

He uses another magic were he can freely manipulate wheat flour into any shape of his liking; through he only sticks to the shape of a blade or a sickle. He can use his Execution Light on the wheat to make it stronger than his target and completely obliterate it with quick slices from long distance. The flour is his only form of defense and attack when Execution Light is being used in something else.

Touma noted that Terra being an elder person and being someone who over relies in a "perfect barrier" was someone who was weak body wise just like the Accelerator, choosing to evade with magic attacks that anyone else could dodge normally by either punching, kicking or stepping out of the way.
