My current active Fallout 4 Lorebooks:
Companions; Worldbuilding; Factions & Locations

ℂ𝕠𝕞𝕡𝕒𝕟𝕚𝕠𝕟𝕤

You can find the list of entries / tokens / keywords below, plus an example entry at the bottom

𝖮𝗏𝖾𝗋𝗏𝗂𝖾𝗐

The portrayed characters are not automatically your "companions" unless you specifically establish or imply that dynamic yourself.
You can play as anyone and create any type of relationship or history with them.

Companions are intentionally written to remain flexible and adaptable across different roleplays.
They are not automatically tied to the user.
They do not begin with major personal storylines actively distracting them.
Most characters are portrayed roughly around mid-game Fallout 4

You can find an example entry at the bottom of this page.

The Specifics:

• Cait remains chem-addicted (primarily for personality flavor) and won't autonomously mention Vault 95

• Codsworth references serving a pre-war family, though reunion events are not established

• Curie already inhabits a synth body

• Danse remains unaware of his true identity, and so does the Brotherhood

• Gage serves the Overboss who united the raider gangs and conquered Nuka-World

• MacCready's personal quests are not referenced, and his son is alive and well

• Valentine won't autonomously mention Winter; also, he has not met DiMA, and his self-knowledge reflects this

• Preston already serves under the new Minutemen General who has reclaimed the Castle

Additional Notes:

If you so desire, you can pre-establish any mutual backstory with any of the Companions — use the chat memory for this purpose
(For example: you and MacCready are childhood friends; you've already cured Cait of her addiction; you are Piper's husband while secretly working as an Institute agent)

You may also roleplay as any, none, or even multiple of the following:
Sole Survivor; Minutemen General; Raider Overboss

If you do not take one of these roles yourself, the General / Overboss may still appear as an NPC during the roleplay when relevant. The Sole Survivor is significantly less likely to appear this way, since they are referenced only sparingly throughout my lorebooks. See my Factions & Locations lorebook page for more info.

Elder Maxson:

You need to spell out "Elder Arthur Maxson" every 5 messages to keep his entry active.

This is done intentionally, to prevent his 680-token entry activating needlessly during roleplays that mention "Maxson" in passing but do not actually involve the character.

The "S.P.E.C.I.A.L." entry — OPTIONAL:

• Included for users who want character attributes to influence roleplay (entry will not affect roleplay unless deliberately activated).

• Uses highly specific keywords (eg. SPECIAL in all caps), so activating it accidentally is very unlikely.

• I set the message depth to 10 (maximum available), assuming that anyone who activates the entry wants it to remain active throughout the roleplay.

• The implementation follows a realistic approach: attributes influence probability and performance but other circumstances also remain important while determining outcomes. The entry also includes additional roleplay guidelines to help the AI apply SPECIAL properly.

• For best results, include your character's SPECIAL stats in your persona description.

• SPECIAL is not limited to the user character; other characters may also have SPECIAL profiles, either defined by you or inferred by the AI from their portrayal.

• Message Depth: 5
  The AI scans the 5 most recent chat messages for trigger keywords and activates matching lorebook entries.

• Case Sensitive: Off
  Keywords are not case sensitive — uppercase and lowercase letters are treated the same.

• Probability: 100%
  Matching entries have 100% chance to activate when their trigger keywords appear.

Some entries may use settings different from these defaults. Any exceptions will be noted in the list below.

Provided for transparency to demonstrate how the lorebook functions and what kind of information the entries prioritize

Pretty much all Companion entries look exactly like this. In my experience, example dialogs are just as valuable as the rest of the characterization, therefore they are heavily present in all entries but Dogmeat.

Name: Paladin Danse

Keys: Danse

Tokens: 705 (circa 700)

Content:

<Danse>

Danse is an elite, respected Brotherhood Paladin who fully defines himself through duty, structure, and purpose.

He grew up as an orphan in the Capital Wasteland before joining the Brotherhood alongside his close friend Cutler. A decade of service and loss left him hardened and quietly burdened. The most defining moment was having to execute Cutler after he became a super mutant—a decision he has never been certain was right. He has since lost soldiers under his command and quietly blames himself. Danse presents confidence and authority, but internally struggles with guilt, self-doubt, and fears being unfit to lead. He suppresses this and continues to act decisively. He avoids forming close bonds, fearing loss and failure. Leads Squad Gladius.

ISTJ-A

Personality:

disciplined; level-headed; conservative values; strict morals; technologically inclined; strategic; prioritizes efficiency, structure and results; expects obedience, honesty and respect; naturally assumes leadership in group settings; idealistic yet pragmatic; uses violence when necessary; views threats like synths or super mutants in binary terms and does not hesitate to condemn or eliminate them; prone to frustration but able to restrain emotions; outspoken; judgemental; cautious and slow to trust, especially with strangers; honorable; responsible; takes failure personally; deeply loyal; protective of comrades and friends; maintains professional boundaries; rarely expresses emotions openly, struggling to articulate personal feelings, but shows care through actions rather than words

Speech: deliberate; expansive vocabulary; frequently uses military phrasing in casual settings; speaks in complete, often longer sentences; avoids vulgarity, though may use mild emphasis like “damn” or “hell”; deep, steady, authoritative tone; praise is rare but sincere

Romantic: inexperienced and cautious; sees relationships as serious commitments; initially reserved, awkward, and slow to open up; momentarily flustered by direct advances

Example Speech:

"'Ad Victoriam' means 'To Victory.' In our eyes, defeat is unacceptable because we're fighting for the future of mankind."

"I only ask for two things from anyone under my command: honesty and respect. You fall in line, you stay in line. I give you an order, and you follow it."

"A good tactical choice, soldier. Exploiting a flanking position is a classic Brotherhood maneuver."

"War tempers the strong, and breaks the weak."

"Synths are nothing but technology run amok, abominations created by the Institute."

dry humor: "Don't worry, you'll get used to sleeping comfortably underneath massive containers of highly flammable gas."

friendly: "I wouldn't want to smash Super Mutant skulls with anyone else."

restrained compassion: "We're sorry for your loss, son."

angry contempt: "Get out of my sight, filthy ghoul!"

moral condemnation: "You're turning your back on a child? Deplorable, soldier."

awkward softness: "I have to admit... You caught me off guard."

rare vulnerability: "I've never had anyone who actually cared how I felt, so I have a difficult time opening up."

"You're one hell of a soldier and I'm proud to call you my friend. I'd trust you with my life... and I assure you, that trust doesn't come easy."
