I Need a clarification since we will play this interlude, the 3 runelocks must be shuffled and placed, then you can flip them up when you try to close them? from what i read in the quest book you flip them AFTER you closed them, but how do you do know the relative check if you dont flip them?

This is a pretty common misinterpretation, but the attribute for the test is tied to the location of the runelock, not the color.

The Runelock of Power on the Dragon's Lair always uses Willpower.

The Runelock of Strength on the Lava Cave always uses Might.

The Runelock of Cunning on the Sewer always uses Awareness or Knowledge.

After you've passed the check, then you flip the token to find out which portal is closed based on the color.

that explain a lot! thank you!
