Alternipedia canon

The Alternipedia canon is the collection of sources and embellishments on these sources that make up the Imperial database. Sources of Alternipedia canon are separated into three main tiers.

Tier 1 sources
Tier 1 or primary sources are the most important sources of Alternipedia canon, and overrule any information from any other sources. Homestuck, as the source of all concepts in the Homestuck universe, is the most relevant and important tier 1 source.

Tier 2 sources
Tier 2 or secondary sources are the second most important sources of Alternipedia canon. Works contributed to directly by Andrew Hussie beyond Homestuck but within the Homestuck universe are all considered tier 2 sources, and are considered canon as long as they do not contradict tier 1 sources.

Important tier 2 sources include:
 * Posts from Andrew Hussie on social media
 * Hiveswap

Tier 3 sources
Tier 3 or tertiary sources are the least important sources of Alternipedia canon. Two main types of tier 3 source exist: works with minimal contribution by Andrew Hussie but still concerning the Homestuck universe and endorsed by What Pumpkin; and works contributed to directly by Andrew Hussie but unrelated to the Homestuck universe.

Tier 3 sources may be considered canon if they do not contradict tier 1 or 2 sources. However, a tier 3 source that contradicts a tier 2 source but agrees with a tier 1 source may also be considered for Alternipedia canon.

 * Paradox Space
 * Hiveswap Friendsim
