Eric began developing Ghostmark in 2024 and finalized the manuscript in February 2026 after collaborating with several beta readers, including a native Japanese reader who assisted with cultural authenticity. Early in the process, he decided to incorporate chapter illustrations to draw readers deeper into the mysteries of the story. With 19 continued years of experience in the video game industry at Raven Software, Eric used his background as an Art Director to further elevate the visual world and atmosphere of Ghostmark.
