Wikia can be reluctant to delete wikis, as they can prefer have uninterested users simply leave the wiki for others to adopt. This only really applies to larger wikis with a significant amount of content, though, and since yours is very new you will probably be able to have it deleted.

If you want to delete your wiki, you should ensure that any content you want to preserve has been preserved (copy it to the other wiki, perhaps?) and then go to c:terramonstersworld:Special:Contact. There's a link for wiki closures on that page.
