These are the different worlds of the Periodic Table Universe.

Compound Kingdom


The Hydros system is a binary star system with a brown dwarf on the outer edges of the system. Hydros is the home star system of the Eich-Tuoans.


Eich-Tuo is the homeworld of a race of people made of water. It is a geographically diverse place with mountains, forests, lakes and oceans. They have a complex belief system, based around the different states of matter.

Eich-Tuo has also produced some of the greatest minds of the galaxy, including Professor Stratus – the creator of the revolutionary weather machine. Because of this, Eich-Tuo became host to the Galactic Science Expo where everyone from around the galaxy can demonstrate their latest technologies.


A gas giant with two large moons, one hot and one cold. Fireling lives here alongside other Fire Grunts.

Noble Gas Kingdom

The Noble Gas Kingdom, also known as the Noble Gas Provinces, are a group of seven star systems each ruled by a noble family.

2 Helios

A star system that features a pink gas giant with many moons. Many mystical creatures such as sprites, elves, gnomes and trolls live here.

Princess Cara Bonnie rules a small area in the clouds, but usually spends more time on social media than actually being a princess.

18 Aragonia

A star system filled with quiet villages as well as the famous Math Magic Castle ruled by the rather irritable troll King Troglo Nometry.

The two headed dragon Los Ninos has taken up residence in this system and has a taste for droplets.

10 Neo

Sobek, God of the River Nile, has taken a liking to this area for its resemblance to the kingdoms he used to rule. However, Lord Krypton has tricked Sobek into believing that Droplet and Molly-QL are stealing the crystals.

54 Xenia

The infamous pirate Captain Salty Peter has laid claim to the area, proving that being the ruler of the seas can extend to more than one world.

86 Radonia

A heavily industrialized star system. The main habitable world 86 Radonia A is covered entirely skyscrapers. The planet’s global temperature is regulated via a large scale version of the weather machine created by Professor Stratus.

The moon 86 Radonia A1 is about one quarter the size of its parent planet. It has been stripped almost bare for its resources leaving it a barren desert although the planet’s ice caps still remain although they are slowly melting. Deep below the surface of the moon is a series of extensive underwater tunnels where many subterranean volcanos are along with thermal vents that gave rise to extremophile organisms.

Fossil Corp Headquarters is located here. Their chief export was fossil fuels, but the cleaner crystal power threatened to make their trade obsolete. Thus, Lord Krypton invested in them in an effort to reform them into a mercenary company.

The bounty hunter Sill E. Con was hired by Fossil Corp to take out Droplet and Molly-QL.

36 Kryptos
