It sucks energy from the surrounding area to create these affects if the gemstone is put into a lead container it will deflect it. The intent was a natural phenomenon. Touch activates the effects or if a person is trapped within. If a person gets trapped within then they get drained a little each time it creates the portals. To release the person the gemstone has to be destroyed. It can be destroyed by sucking too much energy at once (at least three people have to touch it at once).
