It took me quite a while to parse the map properly, but this is a very reasonable dungeon crawl with some interesting ideas.
I will say that I was a bit disappointed about the use of the title. Knowing Ogun from being an orixá in Yorubá religion and in afro religions in Brazil, I was initially excited about a Ogun Dragonslayer, and it got me wanting to see more ties to the god of war and metal, with maybe some African-inspired themes, thinking the offal maybe being some kind of offering. I guess that’s on me for coming in loaded with expectations, but it is a bit sad that the module doesn’t use the full potential of the name to reinforce the themes.
