13 Month Series

The Thirteen Month Series (13월 시리즈, 13 wol shirijeu; or "13 moon series") consists of an Arms Inventory and 12 Ignition Weapons made by a craftsmaster, Ashul Edwaru. They are bestowed by the King Zahard to a formal Princess. In fact, the symbolic significance of the 13 Month Series is greater than any other weapon in the Tower. .

These weapons also vary in shape and function. For instance, one is a Needle and another a Hook. Out of these weapons, only the Golden November is of S-rank. The 12 Ignition Weapons, when Ignited by the user, they releases vast amounts of power of the weapon. It is said that only a formal Princess is supposed to be able to ignite a 13 Month Series, though regulars such as Anak Zahard or Baam have proven this to be untrue.

No matter how skilled the wielder is, it cannot force a 13 Month Series to Ignite. Depending on the weapon's personality, it may refuse to listen to its owner. Baam managed to ignite it, however Yuri Zahard was unable to Ignite the Black March.

When weapons of the 13 Month Series meet, they will resonate and their owners can feel it.

Receiving a 13 Month Series
A Princess who has climbed the Tower and became a Ranker, might be chosen to become a formal Princess who is also called a "chosen Princess". Only a "chosen Princess" is eligible to receive a 13 Month Series, as she has proven her ability by climbing the Tower.

Rules binding a formal Princess
When a formal Princess accepts one of the Series, she must abide to a set of rules:


 * 1) She may not give or even lend a 13 Month Series to another person, otherwise it may be be executed by the Zahard..
 * 2) A princess may own a weapon from the 13 Month Series, such as Yuri Jahad or Garam Zahard.
 * 3) A princess can refuse a weapon from the 13 Month Series. Heice Zahard, upon becoming a Ranker, was presented with a 13 Month Series but she turned it down for reasons unknown.

Notes and Trivia

 * The 13 Month Series all have their names engraved on them. The engraving is in Japanese, because their creator Ashul Edwaru uses a language based on Japanese. SIU made it clear there is no significance behind this, as Chinese, Arabic and other languages are also used throughout this manhwa.
 * The 13 Month Series is actually based on the lunar calendar where all months are based on moons.
