Why didn't the Second Army and the Eleventh Army appear in Warhammer 40K?

A legion was wiped out because of the war with Ran Dan's alien empire. The original body does not rule out being killed or captured. The change of the emperor's attitude towards the original body may be due to the incident of two original bodies, and the original body is no longer trusted and no longer consumed energy.

Warhammer 40K is a series of desktop chess games produced by the British game company Games Workshop. The first edition of the rules of the game was published in 1987, and updated to the ninth edition in 2020.

Game features:

The result is reflected in the works, the history is often counted in thousands or even tens of thousands of years, and the fighting nuns with strong Gothic style in the Middle Ages are active in the grand and desolate background; The chaotic legion deeply influenced by the post-war western eschatology; Black North Americans full of hip-hop and street culture.

Like the elves projected by elegant elves in future fantasy settings; Imperial Guard deeply loved by military fans and lovers of World War I history; There are also Tyrone Zerg who pay tribute to aliens, the titanium empire full of oriental colors, and the space necromancer with robot style.

This kind of mixing leads to the extreme exclusiveness of each race in this game, and the forces of each side are evil, or each side has its own "justice", but at most it is different in degree.

For example, the human empire is often regarded as a "just" side. Although there are many good people in it, on the whole, it is a militaristic, indifferent, extremely corrupt, hopeless and extremely exclusive fascist country. However, from another point of view, working all day to assemble rifles is better than working all day and being killed by aliens.
