L2-11f. Tomb of the Square & Flame - Lower Line Seal

The symbol-lock

(player-skill first; minimal rolling)

Correct sequence: Fortubo → Jascar → Wee Jas → Lendor (press in a steady six-count).
Clues:

• The lintel gives the order directly, phrased as verbs (brace → keep → witness → count).
• A faint chime rings when each correct plate is pressed; a thready hiss answers a wrong plate.
• Pressing the Pyremius plate at any time is always wrong (see Traps).

Resolution:

• Enter the sequence on a six-count; on the sixth beat after Lendor, the central ruby dims, inner bars withdraw, and the door swings inward.
• Using the Stonebond token (11b): Touch the token to the ruby, speak any respectful line to Wee Jas on a six-count → the door opens without checks or trap risk.

Fail-forward:

• One symbol wrong: The door locks for 1 minute; a hair-thin Stone Bite nicks the nearest creature (DEX 13, 1d6 slashing, Attention +1).
• Pressing Pyremius: see Ember Sting below (trap) and Attention +1.

Traps & defenses

• Ember Sting (Pyremius decoy): Tiny nozzles under the jamb flare: DEX save 13, 6 (2d6) fire, and the next CON check to maintain concentration is at disadvantage (eyes water).
• Ruby Witness (noise reaction): If three or more Attention have accrued in this hall, a Ruby Custodian (wight) approaches from 11d within 1d4 rounds to “judge the press.”

Inside the tomb (15′ × 15′ chamber)

Features

• Sarcophagus (sealed, but not trapped): Waxed seam with a ruby dot; lid can be slid with two creatures or Athletics DC 12.
• Reliefs:
• Fortubo (square & hammer) on the west wall.
• Jascar (shield-sun over ashlar) on the north.
• Wee Jas (ruby skull-star) east.
• Lendor (six-bar) south.
  Each bears a tiny inscribed line echoing the lintel verbs.
• Heat grate: Narrow, fused; warm air from the Under-Ash (L2-09).

Occupant

• Ruby Judge (Mummy, Suel embalmed) — stirs only if:
• The lid is pried up with shouting/hammering, or
• The Pyremius plate was pressed during opening, or
• The sarcophagus is looted rudely (no six-count, no line to Wee Jas).
  Use Mummy statistics; add Resistance to slashing/piercing from nonmagical, non-adamantine weapons and Advantage on saves vs. Turn if the party desecrated symbols.

Boons, clues & treasure (tasteful, not swingy)

• Vestments of the Lower Line (fine funerary robes; 25 gp value; wearing them grants advantage on one social parley with a Ruby Custodian).
• **Mason’s True-Square (tool, uncommon): When used to align a stone or mechanism, grants advantage on one related check per day; once per long rest, you can set a Stone Bite seam to sleep for 1 minute by tracing a six-count square.
• Seal Ring of Kendor Malis (silver, ruby chip): While worn, you have advantage on checks to understand Old Suloise funerary inscriptions.
• Ledger slip under the pillow: A note naming Kendor Malis, “Lower Line Measure-Keeper,” and a complaint about hot drafts from the east (tie to your Pyremian breaches and L2-11d).

Boxed outcomes

• Correct press, calm entry: One… two… three… four… five… six—the ruby cools; iron whispers; the door glides inward on a breath of warm stone.
• Pyremian mispress (trap): The ruby flashes; the jamb spits needles of flame—hot air scours your eyes as the lock clenches shut.
• Rude disturbance (mummy stirs): Resin cracks like old lacquer. A lacquered hand rises, palm forward in judgment, and the chamber fills with the dry breath of tomb spice.

Suel full funerary kit

• Pectoral of the Ruby Skull-Star (Wee Jas) — silver-and-ruby neck plate (150 gp). While worn, you have advantage on saves vs. charm or necrotic effects inside funerary spaces.
• True-Square of Kendor — palm-sized mason’s square, etched in six marks (uncommon, no attunement). When used to align a mechanism or stone, gain advantage on one related check per day; once per long rest, trace a six-count to suppress a Stone Bite seam for 1 minute.
• Seal Ring of the Judge — silver signet with ruby chip (uncommon). As an action, speak a respectful six-count; for 1 minute undead won’t target you unless you attack or cast a spell (mini-sanctuary, DC 12).
• Lendor’s Count-Rod — six-notched ivory rod (common wondrous). As a bonus action, call the cadence; one ally within 30 ft gets +1 to their next ability check or tool check (6 uses/day, refresh at dawn).
• Jascar Sun-Disc — gold medallion stamped with a sun over ashlar (art 100 gp; uncommon if activated). 1/long rest, as a reaction when hit, add +2 AC vs. that attack.
• Fortubo’s Brace-Nails (set of 6) — iron nails in a bone case (common consumables). Hammer one in as an action to wedge a trap component or keep a stone door from closing; grants advantage on the next check to disable/force that object.
• Ledger-Bones of the Lower Line — six carved tally sticks (common consumables). Break one to invalidate a nearby undead “muster”: Ruby ghouls/zombies hesitate for 1 round, doing nothing but “recount.”
• Ampoule of Funerary Myrrh — thick resin vial (consumable). Smear on a weapon; for 1 minute it deals an extra 1 radiant to undead and counts as holy water for interactions (as per your Mortuary rule).
