Mar Qaroll

Mar Qaroll, also known as Marrow, is an American worldbuilder who created the high sci-fantasy setting Paneidos, part of a greater series called the Compilation of Paneidos. He is currently focusing on The Little Gods, a dark high-fantasy subseries of four novels within the Compilation.


Biography


Mar was assigned female at birth and grew up in southern Connecticut, USA to a Muslim family. He was a creative child, particularly with writing, and could be found scribbling with a pencil on a pad of paper even before he knew his native language.Around ten years old, he took up writing as his constant pastime. He wrote what he called "Daydream Saga Stories", which was his term for fanfiction. These stories were often more mature than his demographic. In his teen years, he took writing more seriously, hoping to be a professional novelist. He created several initial versions of stories during this time, such as Inverse Sequences. He also created his then-passion project, PHE, which served as the catalyst for and is the predecessor of Paneidos.In October 2019, after many years of disappointment with his fanfiction, he made the decision to stop writing fanfiction and focus on a project he had named in 2013. He eventually decided to take cues from PHE and remove the fanfiction elements to form original work. This project would become Paneidos.

Influences


Mar has several influences for different series within Paneidoverse. Paneidoverse itself is inspired by the experiences a creative may have while inventing original stories, such as "characters and stories writing themselves". Creative influences include J.R.R Tolkien's legendarium and Eiichiro Oda's world.
