Map:wiki
The wiki key links a mapped feature to its page in this wiki. Its value is a page title, and on the feature's browse page that value becomes a link to the article — the way a city on the map connects to its write-up here.
How to tag
Set wiki=<Page title>. Spaces and underscores are interchangeable, so wiki=Sea of Sihia and wiki=Sea_of_Sihia reach the same page. This is Yezur's own cross-reference; there is no link to any outside wiki.
