Sanmran Portal Network

The Sanmran Portal Network (Tirina: Delarn Kisael ni Sanmra, lit. Portal Transportation System of Sanmra) is the official government-sponsored portal transportation system linking Sanmran enclaves. The term refers both to the organization in charge of administering the network, and the network itself. The organization is responsible for the creation, maintenance, and shut-down of enclaves between Sanmran enclaves, as well as advising ministers on which enclaves should be open to the outside world and which should not.

The DKS headquarters is located in Sakaran.

Names
Despite having both an official Tirina name and an English one, the network is almost always referred to as DKS by both Tirina and English speakers, short for Delarn Kisael ni Sanmra. It is also often called simply iskinli (lit. spiderweb), a nickname given to the system after the reorganization in the late 1800s, due to its hub and spoke structure.

Layout
Under the modern system, enclaves are organized into backbone enclaves, hubs, children, and disconnected enclaves (or sunor "clouds"). The largest and most significant cities form the backbone, and all connect to each other: Elten, Orsili, Sakaran, and Akoke. Direct access between backbone enclaves and the human world is strictly prohibited. In addition, Elten and Sakaran are both "protected" enclaves (kisa me'konki), meaning they only link to other backbone enclaves and to hubs. (Orsili and Akoke both link to child enclaves.)

"Hub" enclaves are simply those that have links to multiple other enclaves. The term is generally applied to enclaves with three or more links, but can also be used for those rare enclaves with just two links. (e.g. Kahor, which links to the hub Saral and the child "El Salvador") "Child" enclaves are enclaves that have a single link, and thus are the end of the line for travelers.

Portals are operated on either a permanent basis (open daily; may be closed nights and weekends) or temporary (open on a recurring basis, typically weekly). A small number of enclaves still have no regularly-operated portals (two in North America, three in Asia); portals are opened on an ad-hoc basis every few months or even less frequently.

Organizational principles
The principles used as a guideline for the reorganization were as follows (amended portions in [square brackets]): 1. Each backbone city must have a minimum of 3 outliers and cannot connect externally. 2. All backbone cities must be connected to each other. 3. All traffic to Elten [and Sakaran] must pass through a minimum of 2 enclaves. 4. All enclaves over [8000] population must connect to the portal network. (original limit was lower) 5. All enclaves under [2000] population must connect externally. (original limit was lower) 6. All enclaves under [1000] population have [regularly-opened] temporary portals. (original limit was lower and did not require a regular portal schedule) 7. All portals leading into the network are inside enclaves, even if the town the portal serves is actually located outside of an enclave. (rare, but a few still exist in Asia)

History
The first formal portal system in Sanmra was developed in the [idk middle ages sometime? 1300s maybe?]. Prior to this point, portals were opened on a more-or-less ad-hoc basis; permanent portals existed between a number of major enclaves but no effort was made to link smaller enclaves. The initial network was developed in a haphazard manner, with new areas being linked without much consideration of the best way to integrate them. At this time, many smaller enclaves still had no permanent portals; temporary ones were opened when deemed necessary, not on a regular schedule.

In [some later century, perhaps the 1600s], attempts were made to modernize and streamline the system by shutting down rarely-used permanent portals and setting up the rotation system by which small enclaves were assigned a specific day of the month to open their portals. This system was only ever partially implemented in Asian enclaves, but was more successful in the newer North American enclaves, particularly those set up after the development of the system.

Finally, in the late 1800s, under the direction of Lıniıl and Asihan, a total overhaul of the portal system was undertaken, shutting down or redirecting a huge number of portal links to create a more streamlined system focused around "hubs" with links to geographically-close enclaves. For example, prior to the reorganization, Elten had over a dozen portal links, as opposed to five today.
