Hey Team,
Just and FYI, ShadowDark does not have a mechanic for passive perception or investigation. So, just because you walk across a space carefully and don't die, it doesn't mean it's safe. >: )
Not speaking of anything in particular, just that I'm only going to interpret you actions as written. Having a look around will only spot obvious things and points of interest only. Or perhaps your backgrouds might note something as "interesting" to one person which might not illicit a reaction during a look around from anther person.
For example, Borgo is "checking the anvil", but for what? And how is he doing so? I'm just assuming he's having a look around for anything obvious. If there had been a trap along the side, I would have determined he tripped it, though depending what kind of trap it was I would have given him advantage on his save, or setup a scene where triggered the trap and would have to extricate himself somehow or bad stuff.
