Part I

**Part I** refers to the Shadowverse for the first five Arcs, ranging from around July 5th, 2020 (the creation date of Secrets Entwined) to December 10th, 2021 (the release of Realms Collide). Lasting for seventeen months, this period of time contained fifty seven books, one non-canon troll book, and three stop-motion series that were not cancelled.

## Arcs

There were five “Arcs” of Part I. Each Arc encompassed a certain time period (for example, Arc 1 took place in 2017 while Arc 2 took place in 2019). Starting from Arc 2 onward, each Arc contained an overarching plot with a finale book (excluding Arc 4).

### Arc 1

Arc 1 was the first Arc in the Shadowverse, lasting from July 5th, 2020, until July 12th, 2020. Lasting only one week, this Arc is the shortest Arc in the Shadowverse. However, if one wishes to take the creation date of The Beginning, February 6th, 2020, and say this is the creation of the Shadowverse, then Arc 1 lasted six months and six days, making it the second longest Arc in the Shadowverse. This Arc contained the first three series, Agent 12, Big Guino, and Edward the FBI Pig, along with a couple of miscellaneous books such as Agent 13. This Arc did not have an overarching storyline, but it did contain a “finale”, that being The Last Hope, a crossover of all three series.

### Arc 2

Arc 2 was the second Arc in the Shadowverse, lasting from July 12th, 2020, until approximately September 17th, 2020, for a grand total of two months and five days, making it the shortest Arc in the Shadowverse. Arc 2 served as the Arc with the most amount of books, and also introduced a grand cast of new characters. Contrary to the first Arc, this Arc had an overarching storyline encompassing multiple novels, with the main antagonist being Addax Zorn. The finale for this Arc was The Shadowverse: The Dark Prophecy.

### Arc 3

Arc 3 was the third Arc of the Shadowverse, lasting from September 17th, 2020, until February 14th, 2021, for a total of four months and twenty seven days. A brief hiatus from September 17th until November 23rd was done until the first book of Arc 3, Redemption, was confirmed. This Arc introduced several new series, including The Chronicles of Puffin and Agent ZERO. Like the last Arc, this Arc also had an overarching plot and finale. The main antagonist was Anthony Smith, while the finale was The Final Battle.

### Arc 4

Arc 4 was the fourth Arc in the Shadowverse, lasting from February 14th, 2021, until May 16th, 2021, although one can argue Arc 4 began on February 5th instead with the release of The Silent Adventures of Agent 7. This Arc lasted three months and two days. A major change of Arc 4 was the introduction of media, with the two notable examples being The Silent Adventures of Agent 7 and Scorpia Rising. Unlike the last Arc, this Arc did not have a finale, but can be said to have an overarching plot revolving around Scorpia, the Time Bureau and Perceverous.

### Arc 5

Arc 5 is the fifth and final Arc of Part I, lasting from May 16th, 2021, until December 10th, 2021, for a total of six months and twenty four days, making it the longest Arc in the Shadowverse. This Arc had a variety of books release all cultivating in the “Finale of the Shadowverse”, which was a two-part series with the second part, Realms Collide, releasing on December 10th. This Arc’s main antagonist was Perceverous. With the release of Realms Collide, the Shadowverse would not release or confirm any books (excluding Tales of the Shifter in March 2022) until the Shadowverse Reboot Event was confirmed on December 12th, 2023, possibly ushering in Part II.
