Help with "yellow is it" quest

[Lam al Adie]

There's a map witha twisted path over the water…
Have you found the orange medallion? Use it to find all the relevant places.

The deep wells are hurting me, the first time I entered I fluked it to the ohmmm dialogue, but I don’t think I picked up anything, it’s not on my list of recovered parts & im still missing a skull, I’ve tried starting over but I can’t work out the sequence again, am I wasting time here? There’s a yellow flag so I assume it’s important. TYIA

You assume right that the skull is important.
Check your quest log if there is line like

An ancient meditating man rewarded you with a rat skull for a wise discussion.

If not then talk to the old man again until he says something besides ommm.

AHHHH, thank you! Patience isn’t my strong point, but I’ve spoken to the man again… now back to the museum

I even found a way to smuggle some cheese into the museum, but that does not seem to change anything

Can you please provide a hint for that? A vague one will do. I started a thread on this subject a few days ago - including speculation about what may result from it - but there's been no response. I'm fairly sure that the cheese would only make a difference while Fraedro is still held captive, which may explain why you didn't notice anything had been changed by it.

I would trade you a hint for a hint, but I think Nut covered your question pretty well -

you don't need to look very far.

Think about why you can enter a cell for no reason.

[Imprimere]

Is there anyone generous to tell me where I should use the Fraedro's key, it's been bothering me for a week now I just can't find it. Can anyone spoil me?

Imagine if you wanted to use your pickaxe...

Hello, anyone can spare a hint as to where the back bone is located please? I've spent many hours back and forth pretty much covering every mm of the rat cave but to no avail

[Antison]

This was designed to consume your time

[Nut]

About the backbone:

In a library you found the back bone of a big rat

Now where was that place again?

[LeoTheDog]

Thanks Nut!

don't recall seeing a library anywhere in the cave, so this must be outside in a nearby town?
