On Vincere, in order to claim land, you need power. To get power, you need to have your cities marked. And to have your cities marked, you need to build a high-quality settlement and then make a ticket in the [#gdp-system](https://discord.com/channels/1531479518907203778/1537785169115619440) channel. There are six levels to a city - with the first being just a lowly settlement, and the final one being a metropolis. More information about that can be found in the next tab. #### What are the general requirements for cities? A city does not necessarily HAVE to be in the style of the late 1400s and early 1500s as the server takes place, but there should not be huge skyscrapers or futuristic architecture genuinely unfitting of the time. However, architecture that is truly accurate to the time period will receive a technical bonus. You can't just place 10 buildings (the req for T1) next to each other - the buildings should be well-connected, varied, and have a lived-in feel, with solid interiors. A city's tier is judged via our custom-built plugin that fully eliminates staff bias. #### Other Builds Outside of just cities, you can also build a port and get it marked. These will give small extra claimpower boosts and offer other movecraft-based advantages outside of just claimpower. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://vincere.gitbook.io/vincere-docs/gdp-overview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
