When there is a connection made between the skull and the pedestal, the crystalline cranium begins to glow from within. This radiance spreads down the pedestal and into the ground and moments later to the free-standing archway. The interior of the arch transforms with the glow. A runed portal appears in the eye of the arch and opens to reveal a glimpse of another realm.

A platform of dark stone and beyond buildings shrouded in the shadows of night.
