House of Steel: The Honorverse Companion is the first Honorverse compendium work, released in May 2013 to coincide with the 20th anniversary of the release of the first Honor Harrington novel, On Basilisk Station.
Due to the sheer size of the Honorverse, the decision was made to focus on Manticore and Grayson for the first companion. If it is a success, the next issue would feature information about Haven, the Andermani Empire, and Erewhon.
The name-giving centerpiece of the book is the short novel I Will Build My House of Steel, which is essentially a biography of King Roger III of Manticore and the impact he had on the Star Kingdom politics and military strategy.
The second half of the book contains the actual companion, giving detailed information about the Star Kingdom and Star Empire of Manticore as well as about the Protectorate of Grayson. Along with information about governmental and military organization structures, there are character lists, starship class lists, and numerous illustrations.
The in-universe date of publication of the fictional reference material can be placed between March and July 1921 PD.
David Weber released the first snippets of the compendium in May 2012, in the form of letters from young Roger Winton and Edward Janacek to an RMN bulletin.
The cover art was released a short time later when the book became available for pre-order at Simon&Schuster publishing house.
