OMF and its related stories have grown a lot over the years. As a result, there are a plethora of characters, objects, and places to remember which ... isn't always easy. To help you out, I started creating a few resources this year like a proto-map of the immortal realms, a timeline of the events before the beginning of OMF, and a quick reference guide for when you want to look up anything OMF-related.
To make finding these easier, I have now added a resource page to my website that collects all the relevant links for you: https://yansusustories.com/resources/
The resources aren't finished but I add to them here and there whenever I have a little time. Currently, I am working on the Volume Overview for OMF to make the series a little easier to navigate.
PS: The page also contains links to a guide for Like a Ray in My Night and another guide for the Onion-Cutting Ninja respectively. Also, if you want me to add anything, feel free to comment or message me at any time! I'm always happy to update what is most needed or answer questions here on Wattpad as well :)
