So what is this exactly?

Hello there! this is my submission for Anthroyd’s “Make a Good Map 7” contest, also referred to as MAGM 7. This contest revolves around a 30-day game jam where participants are tasked with creating a brief game set within a specific area comprising multiple sub-maps.

Participants are provided with a designated theme or type of map to construct, such as an island, rural route, or castle, among others. Additionally, a range of gimmicks is presented from which participants can choose. The map itself needs to incorporate both opening and closing credits, appropriately acknowledging the assets and resources utilized in the process.

The chosen theme for MAGM 7 was “tourist trap,” and the gimmick I opted for was “Something is off. You want to investigate?” The resulting creation, “Pokémon: Shiron Castle,” serves as a prequel narrative to my current primary hack. It draws inspiration and concepts from the primary hack. The selected theme and gimmick harmonized well with the sort of atmosphere and enigmatic elements I enjoy incorporating into my writing. Consequently, this is why I decided to base my submission on this particular theme and gimmick.


You take on the role of a delivery boy assigned with the task of delivering an item to an individual named Javier in Daiman Village—a small, history-rich rural settlement nestled within the Tauron region. Upon arriving at Javier’s residence, you discover that he has ventured to the nearby castle situated west of the village. He departed due to a sense of unease emanating from the castle, leading his concerned mother to request your help in locating him, given his extended absence.

Your journey takes you to the castle where an unexpected scene unfolds: the lively “ancient battles fair.” This bustling celebration commemorates the transformation of the Shiron region into modern-day Tauron following the downfall of the tyrant King Tasqui-Shiron and the dissolution of his monarchy. Inside the castle walls, various challengers await you. Among them are channelers striving to commune with the castle’s spirits to glean insights into its history. Additionally, knight cosplayers, specializing in training steel-type Pokémon, stand ready to test your skills.

As you progress, you delve into the depths of Shiron Castle’s history, the broader narrative of Tauron, and the intricate tapestry of past alliances and conflicts, both internal and external to the region. The road ahead holds numerous revelations. Will you uncover Javier amidst the castle’s expanse? To unfold the complete story, I’ll refrain from revealing too much and urge you to immerse yourself in this narrative-driven adventure. Enjoy the experience as it unfolds!
