1: [Castle 01 - Basic Castle]
Singing takes a lot of energy, and monsters need sleep! The Basic Castle really isn't very comfy at all; the rain gets through, it's drafty, and cramped.
2: [Castle 02 - Modest Castle]
It's great to have a good night's sleep! The Modest Castle is dry and warm, but small.
3: [Castle 03 - Comfortable Castle]
Ah, some elbow room! The Comfortable Castle even has indoor plumbing.
4: [Castle 05 - Spacious Castle]
The Spacious Castle has lots of room for Monsters to relax and refresh.
5: [Castle 06 - Luxurious Castle]
It just doesn't get any better than this! The Luxurious Castle has everything a Monster might enjoy, from cold slime pools to dark, nasty dungeons. Who would ever want to leave?
6: [Castle 07 - Extravagant Castle]
This state of the art domicile goes way overboard when it comes to spoiling the Monsters... Personal assistants to wait on them hand and foot (at least those that have hands and feet), the spiffiest sound systems on the Monster market... They've got it made in the shade.
7: [Castle 08 - Paradise Castle]
After agreeing that more beds equals more fun, the Monsters set out to create the most capacious castle ever - and what better inspiration than Gold Island's own Crystal Castle? Following extensive study of the original architectural marvel, the multiverse's finest architects were tapped to craft the new castle in its image. After the smoke cleared, there was no question - this is the be-all and end-all of monster living arrangements. Welcome to paradise!
8: [Crystalline Castle - Natural Islands]
Thanks to mineralogical acumen supplied by Fire Monsters, this Island's residents knew exactly where to dig to find vast deposits of this Natural Island Crystal, a crystal once found in abundance back when the island was an Elemental Land of the prehistoric Continent. Combining the raw strength of the crystal with modern lapidarian techniques has resulted in this magnificent Castle, furnished with more Beds than ever before.
9: [Pyrozite Castle - Fire Islands]
Because of their prolonged separation from the surface, and time spent underground, Fire Monsters became the resident mineralogical experts of the Monster World. While such crystals as Vegedian and Frozium still exist in copious quantities if you know where to look, the Fire Element's crystal, Pyrozite, is far rarer - only a few meager veins have survived to the current day. Luckily, the Monsters were able to scrounge together just enough from the area near the living core to fashion two Castles for the Fire Islands, with enough Beds to support their growing populations.
10: [Crystalline Castle - Magical Islands]
Even though Magical Island crystals are among the ancient Crystals that once erupted forth from the world beyond the Prism Gate, it luckily still behaves in mineralogically expectable ways! With the guidance of the local Fire delegation, the inhabitants of Light Island gleaned how to build a series of glorious Magical Island crystal Castles, ones which perfectly complement the local color palette and provide the beds needed for the island's growing population.
11: [Crystal Castle - Gold Island]
Although shaped like a Castle, this mysterious Structure actually serves as the main power generator for the 'higher plane' of the Monster World! It's from here that the Monsters of Gold Island derive their musical inspiration, as well as their tireless energy so that they can keep singing forever!
12: [Composer Castle - Composer Island]
The Castle on Composer Island is styled after another famous Structure in the Monster World, but the similarity is more than skin deep! Just as the Crystal Castle serves as a power generator for Gold Island, the Composer Castle acts as a powerful transmitter for the creative energies flowing in from the human universe - it's got some of the Seam's best upload/download speeds!
13: [Amber Island]
Unsurprisingly, the Castle of Amber Island is bound by the same peculiar physics of the higher plane as Gold Island's Crystal Castle, and arranges itself in the same multi-faceted, crystalline structure as it grows skyward. What is different, of course, is the building material: hardened sap from the multiverse's World Tree, the Stablo Mjehurića, that preserves musical musings in coagulated Relic form. As more Relics are donated to its expansion, more beds become available for the Fire Monsters of Amber Island to take up residence.
14: [Hummatite Castle - Mythical Island]
Because more Mythical variants were being discovered all the time, the Monsters of the Dreamspace sought to make everybody a little more comfortable. Their first few suggestions left a little to be desired... Exemption from chores? Surprise unbirthday parties? Monogrammed towels? Despite the boundless imagination evident in these ideas, the best and simplest solution was, unsurprisingly, adding more beds. But how to make this dream a reality? The Cataliszt coyly revealed that its close ally in the creation of the Dreamspace, the intergalactic traveler known as the Dream Crafter, has also dabbled in architecture! Sourcing the impossible mineral Hummatite that can only be formed outside reality, this ultimate Castle upgrade blends in seamlessly with Mythical Island's aesthetic... and, most importantly, brings the beds!
