Elemental Power Gems

Four of these gems exist, each intended on being set into one of three magic orbs: the Orb of Oblivion, the Orb of Golden Death (now lost), or the Orb of Silvery Death. 
Each gem, when touched, transports that character and all creatures within 50 feet to the corresponding elemental node. This function only works if the gate in the Temple of Elemental Evil corresponding to that node is cleared and operational.
These gems can be placed within one of the Orbs (Oblivion, Golden, or Silvery Death), which enables their full powers to be utilized.
These gems are not destroyed when the Orb they are set into is destroyed. Instead, they are flung back into one or more of the elemental nodes.
