The Beaked Dragon is unable to ascend the second flight of stairs, because its body is too wide to fit in the space going up the second flight of stairs!
Also, if something happens where one of the Seekers falls down the stairs where the Beaked Dragon can get to him or her, then probably that character is as good as dead probably!

So you are all probably better off going ahead and walking away from this situation and reporting back to the Ship!
Afterall, if Mad Dog Muldoon wants to get his hands on the rest of the gold, then he can send another group to snatch the remaining treasure!
This was written in such a way to let everyone know why there was only a few broken fingers left on the second landing, because the person probably was unable to outrun the Beaked Dragon, failing to make it to the narrower set of stairs where the Beaked Dragon was unable to ascend to the first landing!
Where Crow now is!
However, you are all free to decide just what you want to do, because the Beaked Dragon will at least ascend the stairs to the second landing, hopeful that some misfortunate turn of events will send someone toppling down the stairs into its waiting maw!
