The theory about the player being evil would sound true if the Dryad wasn’t supporting you in your battle against the squid god and if the Guide never stated that the lanterns in the sky are people celebrating your victory against a boss

[Hasa]

The building sounds from the dungeon, as the lore says, is probably from the mechanic building the 3 mechs for Cthulhu's repairing, not the dungeon enemies

[somegoofballwhohasinternet]

I like the theory that we just showed up one day and started murdering powerful eldritch beings, and people just started showing up to watch the show.

In addition to the merchant talking about selling dirt over seas, the party girl also mentioned that she visited Sweden at one point in time.

I just like to think that the world borders just separates your actual world from your other ones, and when you go back to the main menu and select another one you travel throught it
It's always what I thought, and idk I like it
You can keep your character in all your worlds so it makes sense to me that it can just travel to them just like that

[Izzythemaker]

I thought that the lore was confirmed to be that the golem mind controlled the lihzards after realizing that they were viewed as a tool, and the lihzards instead worshiped the sun.
Edit: This also explains the credits where the which doctor and princess meet up with some friendly lihzards.

I dont think the terrarian is a evil or good force; i think theyre a neutral force. They do both bad and good; they do tear up alot of the world but they also kill alot of evil forces, clean the world of crimson/corruption and kill cuthulu again.

[ThatRussianFloridian]

Fun fact: the bestiary entry for the enchanted sword states that it cleanses the world of evil, but it attacks the player, implying the player is evil

[Mario_Mimic]

Imagine if somebody made a mod that lets you travel to other islands. That would be insane.

[pantasticalB.I.C]

It is said that the land of Terraria is one either a really small, medium, or large island.

I would say the final theory is pretty wrong. Terraria's lore states "Cthulhu sought to bring about destruction and domination, before an ancient race of Dryads waged war against it and crippled it by ripping out its organs. Cthulhu then retreated to the Moon to heal and prepare for its next attack." And due to the Engineer's quotes the Lunatic Cultist wanted to heal Cthulhu by making mechanical parts aka the 3 mechanical bosses. So we saved Terraria by killing Cthulhu. Also Redigit, the owner of Terraria, stated that Moonlord is Cthulhu. Meaning we are the heroes saving Terraria. As for why the lihzahrds attack you that is simple. They are acting out of fear. In the end credits we see the Witch Docter and Princess make peace with a few lihzahrds. The Pillars could be a seal on Cthulhu made by the Dryads. This could be confirmed because when you kill Lunatic Cultist's followers he shatters a Celestial Sigil, interestingly the sigil has none of the Pillars' dust that we need to summon him. However we aren't evil for killing the Pillars. Their Bestiary states them as "terrifying tyrants". There will most likely be ANOTHER last update (Who knows if it is really the final one) and we might get more lore from it. Who knows.

“Hey did you hear about the guy who killed that big slime thing?”

“No, but that sounds cool I guess.”

“Yeah I heard he’s gonna fight the eye of a dead god next.”

“Haha…what?”

“That big floating eye that shows up sometimes, you know right?”

“Yeah the Eye of Cuthulu…how he’s gonna kill it?”

“Stab it.”

“It’s a giant floating eye…”

“I dunno man he did pretty well against that slime. And I heard he has some new green shoes!”

“He’s going to die.”

“Pfft, you’re just hating bro.”

“Whatever man, talk to me again if he does it.”

I like to think that the world of terraria is very large, and the "overseas" are other player islands. Its a cool concept if you think about it

[notthnoob]

I am agreeing on all of this exept the lihzard part because at the end of the story ( after moonlord ) you can see the witch doctor being friendly with 2 of them for some reason. And yet still we made peace by killing the bosses. I think the starting point for all of the lore is at the ending where everyone is happy and try to piece things together

[purp]

The wall of flesh is the guide testing if we could handle the spirits, and we take the wof's place as a balance, by removing hallow and corruption/crimson

[thekingofgreen]

i think the reason our character cant go beyond the world borders is because their objective is to kill cthulu (who i think is the same as moonlord just moonlord being an incomplete version) and get rid of the world evil so the character just refuses to leave

[paristracy]

i think the gods realized that the terrarian was too powerful when they made them. the terrarian would skew the balance of any experiment the gods ran, so they stuck them on an island with barriers made to keep them in where they could have fun and stay distracted while the gods did their work.

[clayday]

I love when small youtubers make this much effort, it is always what makes them grow. Effort rewards.

[ItsFusion]

Imagine if relogic made their game with a bunch of random clues just to see how the community would piece things together and create lore

4:43 skeletrons bestiary entry says "bones of a former tyrant pulsed with hatred so strong it left behind a mighty curse upon the dungeon." Get out-nerded
