It’s a lo-ong time since I read it, but aren’t Ponse and Memtok black? Ponse certainly looks black in that illo, and whereas it’s difficult to tell what race Memtok is meant to be, I’m getting a strong Luke Cage vibe off him and that wand kinda reminds me of an assegai.
“Cover up” seems a bit strong; it’s not like it’s not plain text in the story itself. Clumsily so, even.
