Portals are magic teleportation devices that allow a user to leave one hex and enter another instantly. They may be an example of Hat Magic, though they are considered Titanic in nature, likely beyond the power of even an ordinary caster link. Portals take the form of glowing doorways, and vary in color.LIAB_57:12
The only known portals connect to the Magic Kingdom. One exists in each capital city with an associated endpoint in the Portal Park of Magic Kingdom. It's always located near the bottom of the city's tower.
The specific portals in the Magic Kingdom correspond to cities rather than sides, so they will shut down, if the city ceases to be a capital (either being conquered by another side or having the side's ruler change the capital to a different city). The portal's colour, however, is tied to the side. For example, once Gobwin Knob's capital was moved from Gobwin Knob (city) to Spacerock, it's Portal Park green endpoint appeared on the "Spacerock" location, where the Jetstone's blue portal used to be, and disappeared from the previous location.Erf-b3-p138 Casters that belong to a side can always naturally find their way to their side's portal in the Portal Park by what feels like a gravitational pull.WB2014 Digdoug - Episode 8, IPTSF Text 21
It's not known whether there is an active portal in Portal Park not leading to a capital of some side.
Known colours of sides' portals:
- Gobwin Knob (green)
- Jetstone (blue)
- Unaroyal (magenta)
- Homekey (purple)
- Charlescomm (orange)
- Transylvito (chartreuse yellow)
Underneath each portal (both in Portal Park and cities) there's a column going underground that remains even after the portal is shut down.WB2014 Digdoug - Episode 19 This, with the mechanics of portals changing on switching capitals, means that there should probably be a column in Portal Park corresponding to each capital city site. Probably, exactly 99 — the number of sides Erfworld supposedly "started with".
A non-caster unit that attempts to walk through a portal to the Magic Kingdom will be disbanded, and vanish. This is how Queen Bea of Unaroyal committed suicide. However objects can pass through, notably this includes bodies (that can be uncroaked/decrypted on the other side)LIAB 112. It's also possible for Archons (and probably other units with caster special) to at least exit portals.Hvs.tCF 138
Passing through a portal does not follow the known Movement rules. It apparently does not require movement points, as proven when Parson was able to use a portal despite being a garrison unit with zero move. Further, units may pass through the portal when it is not their turn, because Parson and his casters leave Gobwin Knob during the Royal Crown Coalition's turn, and return during the night (between turns).

The backside of a portal looks identical to the front end, but unlike the front cannot be passed through.
It is possible that Carnymancy can bypass portal disbandment. Janis speculates that Parson is able to enter the Magic Kingdom because of natural Carnymancy, and Charlie, the world's most powerful Carnymancer, was somehow able to modify his portal to allow non-casters and projectiles through.
The city of Charlescomm is powered by Shockmancy in about the same way the real world uses electricity, and Lilith was somehow able to shutdown power throughout the entire city by firing into the portal's column. It is possible that Charlie has figured out a way to use portals to generate Shockmancy.
It's known that a golem can cross Charlescomm's portal in both directionsHvs.tCF 1, Hvs.tCF 2, but it's not known if this is because golems are mindless (can be compared to objects) or just a feature of this exact portal. It's also possible that golems can exit MK through any portal, as Parson was mainly surprised that it could enter back. There are 3 stealth golems that serve scouting duty around Spacerock, but were manufactured by Ace, Jack and Isaac in magic kingdom — we can assume they exited GK portal.
