What Is TopicLink?

I noticed the following markup and would appreciate a brief explanation as to what is happening here.
    @helper TopicLink(Topic topic)
I have searched on TopicLink but cannot find it referenced in any classes. I am likewise confused by @helper as I don't understand how it is constructed. Neither term seems to be related to the page's model.

It's further up in the view, it's not in the class library. Helpers are shortcut blocks of code you can use in the view. I'm usually not a fan, but this instance seemed like reasonable use.
