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.
