Serpent Men Empire of Thutothmes Part of The Inner Earth Sword & Sorcery Campaign Adventure Using both Castles & Crusades (C&C) & Amazing Adventures Rpg

 In the sword-and-sorcery tradition adapted for Castles & Crusades (C&C), the Empire of Thutothmes represents an ancient, dark relic buried in the subterranean reaches of the Inner Earth. Sitting beneath forgotten ruins and subterranean vaults—such as the outer levels of deep city-states like Vaar—the empire is a remnant of the primordial age when cold-blooded reptilians ruled the surface before humanity's rise.



Key Lore & Background

  • Origins & History: Millions of years before human civilizations took root, the Serpent Men (or Ophidians) dominated the world. Driven underground into the lightless caverns of the Inner Earth, they built dark, vertical enclaves. The domain of Thutothmes serves as a bastion for their lingering power and high-sorcery alchemy.

  • The High Priest: The empire is ruled and guided by High Priest Thutothmes the Venom-Tongued, an ancient sorcerer-priest dedicated to the slithering primordial deities (such as Set or Yig).

  • Ideology: The Serpent Men view warm-blooded humans as invasive, inferior "chattel," livestock, or candidates for dark biological experimentation. Their ultimate ambition is to tear down human kingdoms above and reclaim their ancient global dominion.

Species Traits & Mechanics (Siege Engine)

When running Serpent Men in Castles & Crusades, their stats and unique mechanical traits emphasize stealth, mind magic, and lethal ambush tactics:

  • Ancient Hatred: +1 bonus on attack rolls against human targets.

  • Cold Blooded: Takes +2 additional damage per die from cold-based magical attacks, but is immune to natural heat and desert exhaustion.

  • Telepathy: Lacking functional vocal cords, Serpent Men communicate silently via telepathy with any creature within 60 feet, and with their own kind up to 120 feet away (even through solid stone).

  • Mental Fortitude: Receives a +4 bonus on all Saving Throws against illusions, charms, and sleep magic due to their alien brain biology.

  • Mask of Humanity (Illusion): Common Serpent Men can cast a powerful, natural illusion to disguise themselves as tall, stiff-featured humans (e.g., Stygian or Hyborian noblemen) to infiltrate surface settlements.

Serpent Men Castes

1. Serpent Man Warrior (Rank-and-File)

  • HD: 4d8 (18 hp)

  • AC: 15 (Natural Scales & Bronze Shield)

  • AC: 17 (Natural Armor & Bracers)

3. High Priest Thutothmes (Boss Encounter)

  • Role: High Sorcerer / Cleric of the Serpent God.

  • Lair Abilities: Can invoke altar effects (e.g., the Idol of Set breathing dim green poisonous haze across the room, forcing a CL 12 Poison Save or inflicting a -2 penalty on all attack rolls).

Structure of the Empire / Dungeon Layout

Unlike wide surface cities, the strongholds of Thutothmes in the Inner Earth are constructed as vertical "wells" of shadow designed to filter out the weak:

  1. The Vestibule of Scales: The entrance hall, guarded by disguised serpent statues that spring to life unless greeted with a secret ritual sign.

  2. The Hall of Whispers: A room filled with telepathic echoes meant to confuse minds and turn party members against one another through distrust.

  3. The Pit of the Sacred Brood: Deep breeding pits filled with swarms of venomous vipers and giant constrictors used to recycle prisoners.

  4. The Alchemical Laboratory: Centers for dark science where Serpent Men brew extracts (such as Black Lotus Extract), distill neurotoxins, and construct strange alien artifacts.

  5. The Inner Sanctum: A massive subterranean cathedral featuring giant golden serpent idols, green flame braziers, and the dais of High Priest Thutothmes.

Alien Treasure & Relics

Treasures found within the Empire of Thutothmes do not resemble standard fantasy magic items. They lean heavily into high-science fantasy and strange alchemy:

  • Venom Distillers: Mechanical alchemical rigs that produce potent nerve toxins.

  • The Thinking Jars: Alien brain-preservation jars that answer dark questions in exchange for a sacrifice of fresh blood.

  • Serpent-Glass Weapons: Blades that never dull and carry built-in reservoirs for coating edge weapons in neurotoxin.

ere is a d100 Random Table of Custom Serpent Man Artifacts and Magic Items specifically designed for Castles & Crusades (using the SIEGE Engine framework).



These items reflect the alien science, dark alchemy, bio-wizardry, and high-sorcery of the Empire of Thutothmes. Many items come with dangerous side effects or corruption risks for "warm-bloods" (humans, elves, dwarves, etc.) who dare to wield them.

100: The Apex Artifact

  • 100: The Serpent Eye of Thutothmes. A fist-sized, pulsating emerald that glows with faint green light.

    • Powers: Acts as a Palantír / Scrying Device that can peer into any location in the Inner Earth or surface world without detection. Once per week, the wielder can open a rift in space (Gate) to summon a Primordial Serpent Avatar.

    • Curse: Any non-Serpent creature holding or attuning to the Eye must make a CL 10 Wisdom Save every week. Failure causes their body to slowly mutate—first losing body hair, then developing scales, and eventually transforming into a mind-controlled Serpent Man loyal to High Priest Thutothmes.

How to Implement in Castles & Crusades (SIEGE Engine)

  • Challenge Level (CL): When saving against an item's special effect, use the target's relevant Attribute (usually Constitution vs. Poison/Acid, Wisdom vs. Illusions/Mind Magic, Strength vs. Grapples). The CL noted in the entries adds directly to the base target number (12 for Prime, 18 for Non-Prime).

  • Warm-Blood Corruption: Serpent Man magic is alien, ancient, and biologically attuned to cold-blooded reptiles. Using these items frequently in your C&C campaign should carry thematic consequences, such as strange dreams, cold skin, or physical mutation over time!
