The Garden of Gizhramut by Gabriela Braams

Down here in the underworld, there is a legend. It is said that, once every so many centuries, a soul would arrive with a rare light within their heart.. And with it, if they were to make the journey to the Gates of Judgement, they would be able to reclaim the mortal life they once lost!
Gabriela created this beautifully crafted comic from scratch as a graduation project. Check out the webtoon here:
