(Spoilers) Lost and not sure where to go

Sorry this probably fairly obvious. So I’ve beaten the first world and got a “strange object” and am at the labyrinth and on the “Strange Pedestal” quest. Whenever I put the strange object in the pedestal my character says it’s not working and I am missing something. I believe I’ve fully explored what was available in the labyrinth and gotten all the items and such but haven’t been able to open any of the doors with the strange object. Not sure what i am missing as I haven’t been able to find where I need to go to get to the next world. Any assistance would be appreciated.
