“Duodentary” refers to twelve in the sequence of primary/binary/trinary etc. Yeah, twelve stars. The char is weird like that (and in many other ways.) And before someone asks, Yes, you can have twelve stars in a solar system. The odds are incredibly slim, but possible. (For those of you who want the numbers, it’s roughly a 0.00000519% chance, or 1 in 19 million, but it’s probably much lower due to how stars form and the like.)
