Forge Worlds with their own Knight Houses

So I was reading something from a social media group the other day, and a friend was coming up with homebrewed stuff for his Knight House and forge world. Apparently his forge world has a Knight House or his Knight House came from a forge world (what's the difference?). Then one fella just came up to him and told him that he got it all wrong. "One thing you need to know is this: Knight worlds are separate from forge worlds. They have close ties with forge worlds, but they are separate."

That, my friends, is not necessarily the case. Forge worlds with their own Knight houses exist. Mars is a prime example of this. House Taranis is a knight house from Mars. And if you read the Adeptus Titanicus supplements, you'll see that there's a few Knight Houses from forge worlds, such as House Sidus from Ryza. So yeah, that's not necessarily the case. If you want your forge world to have its own Knight house, by all means do it! Don't let anyone tell you otherwise.

As evidence, here's some examples from the Adeptus Titanicus supplements, even before I mention the foremost House Taranis from Mars.

Forge World: Mars

House Taranis

Forge World: Mars

House Zavora

Forge World: Ryza

House Sidus

Forge World: Mars

House Morbidia

Forge World: Xana II

House Malinax (this is the rival Knight House of House Yato of Draconis III)

Forge World: Incaladion

House Mordred

Here are the examples of Knight Houses from forge worlds. So next time you create your own homebrewed Knight house and want it to be from a forge world, don't let a lore gatekeeper tell you otherwise! Yes, House Raven comes from Kolossi and has close links to Metalica, House Krast comes from Chrysis but probably has links to Mars as well. House Vulker has a homeworld, Aurous IV, and has close ties to the forge world of Bellus Prime.

But then you can always point to House Taranis, who hail from Mars. If anyone claims that House Taranis is unique and a special case (or Mars, since it's the Holy originator of all forge worlds), then bring up the examples I did. House Sidus of Ryza. House Malinax of Xana II. Don't let them discourage you from homebrewing stuff that is lore accurate, but because they just happen to not read every little bit of the lore (even I won't claim to be a loremaster, no matter how much I read), they mistakenly think it's not. Do it your way! They are your dudes, not anyone else's.

Hope this encourages people to just homebrew whatever they want without having to worry about the relationship between Knight houses and forge worlds!
