On the Subject of Heraldry

Who doesn’t need a coat of arms on their bedroom wall?

See Appendix A for indicator identification reference.
See Appendix B for battery identification reference.
See Appendix C for port identification reference.
See Appendix H for heraldry reference.

This module consists of a book containing the representation of several crests. To disarm the module, select your family’s crest.

Each crest will have three different characteristics that you’ll need to attend to in order to identify the correct one: division of field, tincture and charges.

The Royal House

First, identify the crest of the Royal House. That crest will be the only one containing a charge representing a Lion colored with an Or tincture. Take note of that crest’s characteristics, as well as the Royal House’s family name. The Royal House’s family crest is never the solution.

Royal Crest Score

Use the following tables to obtain the Royal Crest score:

Division of Field Tincture
+2 for each field division +2 if has Gules, Azure or Vert
-1 if has "Party" in the name -1 if has Purpure, Sable or Bleu-Celeste
+3 if symmetrical about the vertical axis (excluding Charges) +5 if has any Stain
Charges Family Name
+1 for each Animal +1 for each letter in the name
+1 for each Cross -1 for each word in the name
-1 for each other charge +4 for each letter in the serial number that is in the name

Obtaining Valid Characteristics

Use the Royal Crest score to identify the correct grid below. If your Royal Crest score is not between 1 and 16, add or subtract 16 to it until it is. Then, rotate the correct grid 90° clockwise for each solved module on the bomb.

The correct grid corresponds to the Validity Table, with cells corresponding to the cells in the Validity Table that contain valid characteristics. Your family’s crest is the only one in the book that contains only valid characteristics.

Other Rules

Metals, Colors and Stains

Tinctures are divided into two main groups: metals (Or and Argent) and colors (all the others). For the purposes of this module, metals are considered always valid. Also, there is a subgroup of colors called stains (Sanguine, Murrey and Tenné). These are much less common than the other colors. Stains are also considered always valid.

The Rule of Tincture

Heraldry is essentially a system of identification, so the most important convention of heraldry is the rule of tincture. To provide for contrast and visibility, metals must never be placed on metals, and colors must never be placed on colors. If a crest breaks the rule of tincture, it is not valid, even if all of its characteristics are.

The Order of the Unicorn

If the bomb has exactly two batteries in one holder, a lit FRK indicator and no Serial or Parallel ports, you are actually an agent of the Order of the Unicorn, and the book contains a secret message for you. To disarm the module, disregard all other rules and select the crest with a Unicorn charge on it.
