Sealed Forest
Overview
The Sealed Forest, a biome that unfolds its mysteries only at the culmination of one's journey. To gain entry into this realm and reforge the dreaded Seal, one must amass a requisite number of Seal Fragments during the course of their odyssey.
New complications such as gaining Hostility when felling trees and facing several Plagues whilst trying to reforge the Seal will undoubtedly challenge even the most experienced of Viceroys! Find Guidance in Small Glades.
Effects
Requirements for Entry
Depending on the Seal type, a Viceroy will need a specified amount of
Seal Fragments to enter the Sealed Forest. Viceroys will also need to be within reach of one of the hex tiles surrounding the Sealed Forest modifier tile. Upon entry, Viceroys have an indefinite amount of years to complete this Biome and close the Seal, no matter how many years they had left in the run.


On the left is a scenario where a Viceroy cannot reach the Sealed Forest, because they do not have the requisite 1 year left to complete a last settlement and then enter the Sealed Forest, on the right is a scenario where a Viceroy does not have enough years left to explore further and reach the Sealed Forest. Thus, a Viceroy is advised to calculate years and
Seal Fragments carefully.
Seal Fragments are earned by Viceroys upon completion of Settlements. Negative Modifiers grant a
Royal Resupply, from where Viceroys can choose to receive 5 additional
Seal Fragments.

Plagues
The Seal is weakening, bringing forth several Plagues upon the world. The only way to stop the Plagues is to reforge the seal by completing Seal orders. An example Plague is The Plague of Mosquitoes, which causes global production speed to be 50% slower.
The first 3 Plagues are always:
- Plague of Mosquitoes
- Plague of Malady
- Plague of Darkness
After that, Plague generation is random.
The Beacon Tower


The Queen grants each Viceroy who dares to enter the Sealed Forest a new Blueprint to be used exclusively in this Biome. The Beacon Tower offers three levels of aid, each containing temporary abilities to choose from. A viceroy can choose two abilities from the first two levels, and one from the last.
Level 1: Supplies (Choose 2)
- 30
Meat - 40
Grain - All Buildings using Fertile Soil will produce 50% more goods. Lasts 3 seasons including current one.
Level 2: Bells (Choose 2)
- Global Production rate is 50% faster for the current season.
- Villagers with low resolve leave 50% slower for the current season.
- All Trade Routes are 100% faster for the current season. (Active Trade Routes included.)
Level 3: Miracles (Choose 1)
- Hostility is decreased by 100 for the duration of the current season.
- The Ancient Hearth's resistance is increased by 250 for the duration of the current season.
- Scouts work 50% faster on Glade Events for the duration of the current season.
Once the tower is built, it cannot be destroyed. Viceroys need
Planks,
Bricks and
Fabric to build it. On Prestige 6 and higher, 3 of each material. On Prestiges 5 and lower, 2 of each.
Strategy
There are some clues in Glades providing Guidance to where the Seal is located. The Seal will always be located in a Dangerous Glade, and Guidance to the Seal's location spawns in all Glades until the Seal is discovered. The Guidance Stones can be deconstructed using the Destroy tool to recover some Stone and Resin.
In order to successfully complete the Sealed Forest, a Viceroy needs to reforge the Seal by completing Seal Orders. All Seals have the same Seal Orders to complete, no matter the color. It is a race against time to complete all the Seal Orders before the Queen's Impatience runs out. Only one order per level needs completion. A Viceroy need not fill up the Reputation bar to complete the Biome as in other Biomes. A Viceroy cannot win the Sealed Forest by filling up the Reputation bar, once the bar is filled, it is no longer possible to lower Impatience.
Guidance Stones can be demolished, granting 15
Stone and 8
Resin.
It is always a good idea to hold in SHIFT while marking trees so you can choose to only chop Overgrown trees, which has 20 charges instead of 2, giving you more wood and less Hostility.
