The old man the ship targeted by the Empire hated by the people that had had that that showed how to destroy the Empire large enough to span the continent making up the whole world a thousand years since creation; the young guard the secret now, but the Emperor the Empress a commoner gave birth to loved will will the assassin the previous Emperor had had died to to take the secret the Ancients the Emperor revered created back, yet that assassin is a part of the Three Beautiful Grand Ancient Sharp White Heavenly Men who saw Her name the world, which means that the assassin works for the people the Emperor oppressed, so that that the Empire the Emperor the Empress ruled ruled would be destroyed by will not be stolen. Spoiler: translated version, modified off westeller's post A few old people run a ship. That ship held a secret to destroy a super-huge Empire. Nobody likes the Empire. The old people passed on that secret to the young people. The Emperor, who is loved by a commoner Empress, doesn't give up easily, however, and will order an assassin that killed the previous Emperor to take that secret back. Unfortunately, the assassin is part of a stupidly named organization opposed to the current Emperor, so the secret that would destroy the Empire will not be successfully stolen. ..... I trimmed some details, like the fact that the Empress "rules" the Emperor and that the Emperor reveres the Ancients who created the secret. Or whatever.

It isn't a run-on sentence; a run-on sentence is a sentence that runs on without the proper punctuation. This is a run-on sentence: This isn't a run-on sentence: The wording is technically correct, but it's hard to understand.
what is the first 'that' referring to here? He had had something, which has to be the first "that". But nothing else in the sentence is actually being referred to here as far as I can tell... had had and that that aren't necessarily grammatically incorrect, but by this context I think it is. You should replace the first that after the had had, unless I'm missing something
In other words, this sentence is not at the longest it can be. Please take this into account on future posts~
Correctness (grammatical) and political (ease-of-reading) correctness are not the same thing. As such, it can be as long and winded as one wishes it to be. But, ease of reading is still a thing, so... Meh.
the ship once had that which... That's a rule of thumb for good writing. This isn't good writing. It's hard-to-understand grammatically correct writing to show how English is a mess.
