How to Use This Expansion

In order to use this expansion, begin a campaign of The Forgotten Age (or a standalone scenario from that campaign) using the setup instructions in The Forgotten Age Campaign Guide. However, when setting up a scenario using this expansion, find the new scenario card titled "Return to (scenario name)" and follow its additional setup instructions as well.

Each of these new scenario cards is included in one of the following encounter sets, which modify and enhance the original scenario:

Return to The Untamed Wilds
Return to The Doom of Eztli
Return to Threads of Fate
Return to The Boundary Beyond
Return to Heart of the Elders
Return to Pillars of Judgment
Return to K'n-yan
Return to The City of Archives
Return to The Depths of Yoth
Return to Shattered Aeons
Return to Turn Back Time

These encounter sets contain new challenges and new versions of old cards. When you are instructed to gather one of these encounter sets, follow the instructions on the new scenario card. Some of these cards replace old cards, while others are set aside or shuffled into the encounter deck.

The insert shows an example of a scenario card, "Return to The Doom of Eztli," as a photograph. Its front and back are reproduced below. The back is partly covered by the front card in the photograph, so fragments that cannot be read are marked in brackets.

Return to The Doom of Eztli (front)

Perform the setup as indicated in The Forgotten Age Campaign Guide, with the following exceptions:

When gathering encounter sets, also gather the new encounter sets for Return to The Doom of Eztli shown here: Yig's Venom → Venomous Hate; Temporal Flux → Temporal Hunters.

Gather the 3 Pit Viper cards from the Serpents encounter set and set them aside, out of play.

Before setup, remove the original Burial Pit, Underground Ruins, and Secret Passage locations from the game.

(Continued on reverse side.)

Return to The Doom of Eztli (back)

Before setup, replace the original Entryway, Ancient Hall, Grand Chamber, and Chamber of Time locations with the new versions from this encounter set.

Before setup, replace the original Harbinger of Valusia enemy with the new Harbinger of Valusia (The Sleeper Returns).

When building the exploration deck, use only Sealed Passage, Mosaic Chamber, Tomb of the Ancients, Throne Room, [...] Pit, Ancient Hall, and Grand Chamber. Do not include any of the other encounter cards listed in the original [...] instructions.

[...] ration of this scenario, the following [...] rule applies: [...] After a successful exploration ends, [...] top card of the encounter deck into [...] deck.

[...] to the scenario reference card [...]

For example: When setting up The Untamed Wilds using this expansion, find the card titled "Return to The Untamed Wilds" and follow its additional setup instructions.

This expansion also includes a Return to the Rainforest encounter set, which should be added to the original Rainforest encounter set during any scenario in which that encounter set is used.

Replacement Encounter Sets

Four brand-new encounter sets are also included in this expansion. These sets are designed to replace four encounter sets used in the original The Forgotten Age campaign:

Dark Cult → Cult of Pnakotus
Expedition → Doomed Expedition
Temporal Flux → Temporal Hunters
Yig's Venom → Venomous Hate
Cult of Pnakotus replaces the Dark Cult encounter set from the core set.
Doomed Expedition replaces the Expedition encounter set from The Forgotten Age.
Temporal Hunters replaces the Temporal Flux encounter set from The Forgotten Age.
Venomous Hate replaces the Yig's Venom encounter set from The Forgotten Age.

When you are instructed to gather one of these encounter sets, it replaces the original encounter set. Remove that encounter set from the game and use the replacement, as depicted.

Variant: Randomized Encounter Sets

As an optional variant, for added chaos and replayability, you may choose to shuffle the old encounter set and the new one together, then randomly select a number of those cards to create a new encounter set. The total number of cards in the new encounter set should be the same as the number of cards in the original set (6 cards for Dark Cult + Cult of Pnakotus; 5 cards for Expedition + Doomed Expedition; 5 cards for Temporal Flux + Temporal Hunters; and 5 cards for Yig's Venom + Venomous Hate).

Additional Explore Rules

Observe the following additional rules while resolving Explore abilities in Return to The Forgotten Age.

If an enemy is drawn from the exploration deck, it is resolved as normal. If it is discarded, place it in the encounter discard pile as you would normally. This is considered an "unsuccessful" exploration.
In some scenarios, there are additional changes to the explore rules. These changes are noted on the setup card for each scenario.

Additional Campaign Guide Instructions

The following are additions to the Campaign Guide that players should read while playing Return to The Forgotten Age.

Threads of Fate

After reading the scenario introduction, but before performing setup, read the following:

Intro 7: As if you didn't already have several other pressing concerns, this morning's article in the Arkham Advertiser piques your interest: "Chaos in French Hill!" The article goes on to describe several strange happenings sighted around the estate of one Marshall Hastings in French Hill, an old and storied neighborhood of Arkham. According to the article's source—who goes unnamed—the mansion has become a tangled mess of overgrowth and serpents. The article reports that a recent expedition returned with several strange artifacts in tow, meant to be displayed in the Hastings manor. You wonder if this has anything to do with your expedition to find the Eztli. Even if these events are unrelated, your investigation might connect you with others who can assist you in turn.

While resolving Resolution 1, resolve the following as well:

If act 3g was completed, record in your Campaign Log that the investigators recruited the help of another expedition. Any one investigator may choose to include the Veda Whitsley story asset in their deck. This card does not count toward that investigator's deck size.
Each investigator earns 1 additional experience for each act 2 and act 3 card that was completed during this scenario, as you gain insight into the schemes of the Brotherhood. Additional experience gained for completing act cards during this scenario (including act 1 cards) cannot be spent to purchase cards. Instead, it must be spent to remove poison or cure trauma, or it must be converted to supply points, as outlined below. Other experience gained can be used to purchase cards and/or for any of these other purposes, as normal.
During the Resupply Point at the end of this scenario, there is no longer a limit on how much experience may be spent to remove trauma. Additionally, each investigator may convert up to 10 of their experience to supply points, at a rate of 1 supply point for every 2 experience converted.

Heart of the Elders, Part 1

While resolving the "no resolution was reached" resolution for this scenario, instead of replaying Scenario V-A: Heart of the Elders, Part 1, the investigators may choose to proceed to the following resolution:

Resolution 2: You haven't yet completed the puzzle of the six pillars that serve as the entrance to K'n-yan, but you don't wish to tarry any further in this hostile jungle. You decide to enter the cavern anyway, hoping that whatever "wards" the pillars represent are nothing but ancient superstition...

You have trespassed in a hostile land. Place pillar tokens on the Mouth of K'n-yan until there are exactly 6 pillar tokens. Then, for every pillar token added in this way, record two tally marks under "Yig's Fury" in your Campaign Log.
As you pass by the pillars, intense pain wrenches its way through your body, and you are afflicted with a terrible curse. Each investigator who is poisoned takes 1 mental trauma. Each investigator who is not poisoned adds a set-aside Poisoned weakness to their deck.
Proceed to Resolution 1.

The Depths of Yoth

While resolving any of this scenario's resolutions, resolve the following as well:

Check your supplies. If any investigator has sticky goop and an investigator "collected a strange liquid," the liquid from the fountain dissolves the viscous substance, revealing a solid object beneath the ooze. Record "Key of Eztli" in any one investigator's supplies.

Achievement List

The following is a list of achievements you may strive toward as you play the Return to The Forgotten Age campaign. These achievements can only be completed while playing with the Return to The Forgotten Age encounter sets. As you complete each of these achievements, check the box next to it. Try to complete all of them for the ultimate challenge!

Expansion Icon

The cards in the Return to The Forgotten Age expansion can be identified by this symbol before each card's collector number:

Note: Some cards in this expansion are alternate versions of existing cards from the core set. In order to prevent players from being able to tell which card is which, the front side of some of these cards bears the same copyright information, encounter set number, expansion icon, and card collector number as its original version. The back side reflects the card's true set information.
