Use {{ZeroLink}} instead of [[Zero]] to get fog (File:ZeroLink Fog.png) over the link. Links lead to Route Zero by default.
Or, use {{ZeroLink|yourtexthere}} to get fog over yourtexthere, e.g. yourtexthere.
To change the link destination (why?), use {{ZeroLink|yourtexthere|destination}}, e.g. this links to Weaver.
For the case where Route Zero should be a link in its entirety, but only the word "Zero" should have the fog effect, use {{ZeroLink|Zero|Route Zero|Route }} (including the space at the end before the }}), e.g. Route Zero.
