So Marco's wand look a lot of like Ludo's (the one with skull and bat wings). We can assume that the wand looks monster-y like... I guess it's because of monster arm.
It does, and even more than Ludo’s, the wings look exactly the same as Buff Frog’s ears! I don’t know what to make of the “ominous” design, if it’s related to Monster Arm or who knows what.
Eclipsa’s wand had “black wings” (and a crescent moon too) as well, but they look way more crow ones than bat ones.
As absurd as it is the closest shape to Marco’s wand so far is the Avarius family symbol, or the wand Ludo imagined in Matchmaker… super weird.
It might also be relevant that he read Eclipsa’s chapters, and that this happened.
