[b]Problems, put bluntly:[/b]

1) You posted in the Advanced Section. Advanced gets the lowest traffic. You minimised your pool before you started.
2) Honestly, it doesn't [i]look[/i] like an Advanced interest check (see #3), so you might well be passed over by people who might think the RP should be in a different section.
3) It really isn't the best interest check in the world. Standards for Advanced are typically higher (ie: potential players expect to see something more impressive), and the level of detail is quite thin. It's set in an original world with barely one paragraph of geographic detail but almost nothing on history, culture, etc. I don't do fantasy, but if I did, I wouldn't have the faintest idea where to begin. The Codex is a great tool, but it's hidden on the fourth post.
4) It also isn't the most attractive interest check in the world. The title is clear but a little uninspiring, and there's no formatting at all. Formatting interest checks means you can lay out information clearly and attractively so people can easily get the information they need.

[b]Solutions, for next time:[/b]

1) Try Casual. If you like big games and want lots of interest, Casual really is your place.
2) If you stay in Advanced, watch your grammar and format your post. Think less 'fun thing to do' and more 'business proposal' until you're confident you know what you're doing.
3) Give a concise description of world-information, plot-information, and thematic information along with a tl;dr that doesn't include references to stuff some people might not get, and give a clear link to any external sources with a 'for more information' message all in the first post. You kind of have all the bits and pieces, but you need to polish them, which brings us to #4
4) Hit it with the Pretty-Stick. [url=http://www.roleplayerguild.com/topics/4959-formatting-interest-checks-and-the-first-ooc-post/ooc]This is a great resource[/url]. Some people just won't read an Interest Check if it's badly-organised and some others (like myself) will find the information very hard to take in. Leave carriage returns between sections. Have headings. If your Interest Check is badly-organised, by the way, it gives the impression that you're a disorganised GM, also known as the worst thing imaginable to the role-playing population.
