There are three types of portals:
|Preview||Type||Location / description|
|Small portal||Scattered throughout the forest|
|Cliff portal|| On the cliff face.|
In Two Crowns it grants access to the cave.
|Dock portal|| At the far side dock in Two Crowns.|
It has a tentacle for extra self defense.
This section describes the general behavior of portals throughout their regular day-night cycle.
The table below defines the states in which a portal may be found. It can be used to describe any portal at a given moment. Opposite states are displayed side by side. A full description of a portal's behavior can be composed by choosing one (and only one) adjective from each row.
| Any portal that is not the closest one to the town on that side of the Kingdom. It can never recognize a hostile presence, it can't be attacked and never opens. |
|The closest portal on each side of the Kingdom. If non-exhausted, it remains sensitive to any hostile presence, being able to open to counter it, even during the day. It opens at night for the regular waves.|
|Active portals become exhausted right after a scheduled wave (nightly waves or Blood Moons) has been lauched. They remain insensitive to any hostile presence until the next day noon. They're still able to react and open if attacked.||Every day after noon, active portals recover their ability to recognize hostile presences, remaining on this state of alert until the nightime moment when the Greed wave has been fully launched.|
| An open portal is filled with swirling, pink and purple goo, and hums menacingly. It is about to or is already delivering monsters to the Kingdom's realm. It launches the waves of Greed at night and spawns a greedling at a time to counter a hostile presence.
|A closed portal has no fluid inside. The Greed cannot pass through it to enter the Kingdom's land. They can go across a closed portal though, if returning to their world (e.g.: a greedling with a coin). Active portals may be closed if exhausted or not disturbed by a hostile presence.|
An archer (soldier or hunter) hitting with one arrow an active portal (exhausted or not), at any time of the day or the night, is immediately considered a hostile presence.
The Monarch or any subject approaching a non-exhausted active portal within a distance of half of screen and remaining on that area enough time (a few seconds) to trigger that portal to open is also considered a hostile presence. E.g.: Monarchs that pass by an active portal galloping on a Stag will not be considered hostile by an active portal because they're too fast.
In Classic and New Lands, villagers recruited deep in the forest, are never considered hostile by portals. They can be caught by regular Greed waves, but they never provoke themselves a portal. In Two Crowns though, it is not uncommon to see villagers triggering portals while trying to make their way home.
Portals can only be destroyed by sending out knights and their party to attack it. Portals do not regenerate health, so any damage inflicted by a knight's party is permanent. Portals that are under attack release a few greedlings. The longer the kingdom has existed, the more greedlings will appear.
When a small or dock portal has been destroyed, a teleporter can be created in its place.
