The Exploring Series
ManggMangg
Lore, mythology, and history summaries in easy to understand and easy to digest formats. The series aren't totally comprehensive, but they provide a great springboard for someone just dipping their toes into a new franchise or topic. So far, I've covered the Cthulhu Mythos, Middle-earth, Star Wars, The Elder Scrolls, Norse Mythology, Celtic Mythology, the SCP Universe, and Warhammer 40k, but I hope to continue doing this for many years.
