Forum:How do I delete a page?

How do I delete my page? If I cant do it, then how do I get my page deleted? Btw if anyone can delete the pages they are: Grassland Hill, Birch Forest, Cave Den.

The template is Template:PSA (I dont want the template deleted just the pages) &#123;&#123;SUBST:User:TruJam/sig&#125;&#125; (talk) 00:26, 2 January 2017 (EST)
