User blog:Amerininja/Umbrakinesis Practice?

So a member here did a remote scan on me recently and proclaimed that they saw a very obvious shadow. I was confused at first not thinking of what darkness really was. I thought it evil and now I know its a huge necessity. So i searched for an Umbrakinesis page. There isn't one, but there is a photokinesis page. Can anyone here give me tips on the ability or is UmbraK just a subset of PhotoK?
