Hoard of the Dragon Queen indicates that there are giant lizards
in "Greenest in Flames" (p. 7): "the streets of Greenest are overrun by forces consisting of, cultists and acolytes accompanied by monstrous allies: kobolds with ambush drakes and giant lizards." In the next paragraph, it reads "Roll 1d8 on the Episode 1 Encounters table to determine each encounter."
The table in question contains:
kobolds, ambush drakes, cultists, guards, acolytes, and townsfolk,
but no giant lizards. I skimmed the chapter a few times and couldn't find anything more on it.
So, why are they listed here if they don't show up in the encounter table?
