A vibrating Strange glowing orb is an item obtained by using the red strange glowing orb on the ancient statue.

If used on Merethiel, it prompts the message "Mazcab? I've not heard of that place before."

It can be listened to for random pieces of dialogue. However, having any type of rune in your inventory will result in the same message: "I wonder... How do those work?".
