Changelog:
Bosses And Enemies
Dr. Erthenton IV
Not much is known on any of the doctors (There seems to be 5, but there could be more), but the little we do know is that Dr. Erthenton is the one who built the Mechanical Terror boss (Either for war, defense, or other purposes). It’s highly possible that he may have built the lab. (See lab section as it’s highly related to this)
(This is a really bad illustration of Dr. Erthenton working on the mech terror)
Goblins:
Goblins have a primitive civilization and will team up on enemies. They are fanatics who serve the Goblin Warlock. They live in camps in the arid grasslands. They seem to have domesticated cornuhorns (The big rhino’s) and rode them for combat purpose.
Gnomes
Gnomes live in the jungle in their small villages quietly. They are boring and like to do nothing. But when provoked they will attack with no mercy. Their origins are unknown, but they could (emphasis on could because its random speculation with no evidence) be artificial creatures.
Ancient Statues
Sleeping guardians that seemed to guard ruins and awaken if a great force disturbed them. Some ancient race likely created them. Always found in the Alpine biome.
The Erthium Eye
The Erthium Eye is the Grand Overseer of the Realms and is a watcher. Probably has a deep connection to Erthium as it appears to be made up of it. (Explaining its power? Since erthium can be used to buy rare skins)
The Mechanical Terror
A war machine made by Dr. Erthenton IV. It is unknown how he made it and why, but it is designed for violence. The strange blue rocks in the upper chamber may be the Mech’s battery. (It’s called crazite, and there is next to no knowledge on it other than it may be used as a power source since there are pipes in it seeming to take something from it)
Biomes
Mossy Cave: A cave filled with moss. There are ruins inside and Erthlings or goblins may have settled there. (When asking castaway about caves he says someone left ruins in there)
Erth 13: A halloween event from the very early stages of the game, its now included in the map as “Crimson Caves” for an xp source, yet again, not much is known about it. (Keep in mind Shattered realmz)
Tundra: A harsh snowy land located far above all biomes. Even in the harsh cold, many creatures dwell there.
Arid Grasslands: Dry grasslands where goblins are located
Plains: Starting grasslands biome.
Lava Cave: Cave filled with lava, was going to be used for Magmus but there’s no lava anymore and Magmus has yet to be worked on. (Magmus was going to be a boss in the lava arena)
Forest: Dense woodlands that was gonna be a deer place
Taiga: Snow area before Tundra.
Jungle: Its the jungle, where the gnomes reside.
Graveyard: A mysterious biome filled with graves and zombies. (was originally used for the zombies gamemode but like erth13 the biome was brought to the map)
Other random stuff
Castaway:
Castaway is basically the npc that helps you when you start in a game (except he doesnt because nobody knows how to use him), he’s a mysterious realmhopper who knows an unsettling amount of information about realmz.io and gives it to you in small pieces if you use any keywords, e.g:
Jungle, thang, paladin, Erthenton, castaway, bug, chicken, savanna, portal, alpine, taiga, erthium(responds the same as hi, hello, or sup), graveyard, whirlpool(responds the same as hi, hello, or sup), birds, saplet, toadstool, caecilian, spike, grassland, crates, amphibians(responds the same as hi, hell, or sup), boss, and weapon. And finally, if you ask castaway “Who are you”, then he will respond “I forgot”, “Who am I”, or “I was here long ago” (There’s an infinite amount of speculation you can make if you want, since castaway is so mysterious)
(look at bro hes so devious)
The Statues
Three statues that each took the form of an insect, a pear, and a feathered serpent.
this image explains it, the pear is just because FuturePearStudios.
Deer
The deer update never got added to the game completely (which I’m grateful for), but if you look in the files there are stick and deer weapons which they were going to use.
Erthlings
Talking about erthlings requires me to go into erth.io lore (which is annoying asf) but basically Realmz.io used to be called Erth2 and pretty much everything was Erth related like Erthium, Erthlings, etc, and when realmz.io rebrand came its too much of a pain to change. (It has little effect on the lore asides from erth.io the game itself)
Realmhoppers
The new name for realmz.io players/characters (I guess it’s more specifically the character, because the player can name it anything they want, but true name is realmhopper, so its confusing)
Might imply that there are other realms to visit (from the erthium eye sayings its the overseer of this realm, and erth13 and graveyard existing, but erth13 is probably just a corruption/break phenomenon where the world was plunged into a mirror thats corrupted), so, uhh, prookl realm when fr fr.
