Thema

If one wants to follow the path of magic, he or she needs a Thema (theme, topic, subject, or matter). Everything starts there and also comes together there. Superbia, Ira, Acedia, Invidia, Avaritia, Gula, Luxuria. These seven deadly sins act as Archives, and within them, you find a thema associated with that archive. Your thema is the thing that's farthest from yourself. So the things further from one's own common sense is what makes true "magic." One's own archive is the opposite of himself/herself. For example, if your thema falls under the superbia (pride) archive, it means is that you have no sin of pride and you have a virtue of humility.

Superbia (Pride)

 * Justitia/Iustitia [Justitia and Iustitia are both correct translations (Justice)] - Thema of Mira
 * Imperium [Impero - another correct translation yet Imperium is most recommended] (Rule [manga] / Control [anime]) - Thema of Arata
 * Verum (Truth)

Ira (Wrath)

 * Ruina (Collapse/Ruin/Destruction) - Thema of Arin and Hijiri
 * Cultura (Culture)
 * Partum (Creation) [Partum in anime and in manga raw version] / Baltan [Baltan in the manga when translated/a wrong translation] - Thema of Hijiri
 * Analysis (Disassembly) - Thema of Hijiri

Acedia (Sloth)

 * Ligare (Bind) - Thema of Selina
 * Infrequentia (Infrequent)
 * Sanctus (Holy)
 * Stagna (Stagnation) - Thema of Lieselotte

Invidia (Envy)

 * Expectatio (Expectation) [Exspecto in the anime 1st opening song but a wrong term] / [Expectatio is the CORRECT term because archives and themas uses LATIN terms]- Thema of Levi
 * Unspecified - Thema of Lugh

Avaritia (Greed)

 * Amicitia (Friendship) - Thema of Yui
 * Sapientia (Wisdom)
 * Frux (Fruit / Result) [Frux can either mean fruit or result yet the word fruit is the closest to its correct translation]

Gula (Gluttony)

 * Fides (Faith) - Thema of Akio

Luxuria (Lust)

 * Abies (Fir) - Thema of Lilith
 * Everlasting
 * Vanitas (Emptiness) [Fall in the manga yet the proper translation is Emptiness] - an ancient lost thema - Thema of Abyss Trinity
 * Terminus (Limit) - a lost magical thema - Thema of Anastasia L

Extra Thema

Victoria (Victory)- When Arin's Demon Spear Gae Bolg is transformed into God King's (Odin's) Spear Gungnir using Limit Release, she will gain this extra thema with the support Yui's Arc Symphony.

TRIVIA:

The term Baltan in the manga is a wrong translation of a fan. Because of the very small characters beside the larger complex characters (Kanji) that is found in Volume 2 Chapter 20, they mistook the word. There's a "ha character" in Japan where you can translate it into "Ba" or "Pa" when you add a specific symbol. Same goes with "Ru/R" and "Lu/L" too. The translation is not now fanmade, it has an original source, a teacher of Japanese language. So Baltan in manga does not really exist, that's why it was stated in the anime that it's Partum (even without using subtitles).
