The text on this page has been transfered and changed where necessary from MSPA Wiki.Derse, also known as the Dark Kingdom, is one of the two kingdoms in the Incipisphere. Derse wages an unending war against the Light Kingdom, Prospit, striving for the destruction of Skaia. Derse is destined to defeat Prospit, forcing the players to kill the Black King on their own to prevent Skaia from being destroyed.
Derse is a shadow-cloaked violet city planet that orbits Skaia from far away, outside of The Veil, and is connected to its single moon by a large purple chain. Derse is ruled by the Black Queen, and the planet is inhabited by black-carapaced citizens who resemble black Chess pieces. A series of spires exist on Derse, one for each player in a session of Sburb. The tops of these spires contain the data from pre-entry Kernelsprite prototypes. As the players prototype their sprites, the spires activate and the prototypings are applied to the monarchy and underlings of Derse. Note, though, that only prototypings that occur prior to a player's entry into The Medium are stored in the spires of Derse.
The moon of Derse possesses a series of towers, one for each of the dream selves of roughly half of the players in any session. The other half of the dream selves reside in similar towers on the moon of Prospit. These towers contain rooms that very closely resemble the bedrooms of the players in their home world, except they are portrayed largely in a single color tone associated with the player's font color in Trollian.
The Dark Kingdom has a King and a Queen who are the highest in command. The Queen has a Queen's Ring with orbs (one for each player in the session) representing the spires Derse. As long as she wears her ring, she is physically affected by the prototyping of each player's Kernelsprite, the bearer of the ring gains additional power.
Similarly, the King possesses a scepter with orbs around its larger end, like the Queen's ring, and a large orb that resembles Skaia on top. He is also affected by the players' prototyping, and his physical size also increases significantly with each prototyping.
The Black Queen resides within the halls of Derse, overseeing administrative and political duties, while the Black King fights the perpetual war against Prospit off-planet in the thick of The Battlefield.
One very high ranking officer is the Archagent, who is in charge of the most tedious paperwork, like handling parking tickets and illegal parcels. He can also command Agents and Underlings. He also does surveillance through his cubicle. Jack Noir is the only known archagent and implied to be the only Dersite to hold the rank.
An Agent is a relatively high-ranking member of the Dark Kingdom, who has a wide range of different duties. While some work as a sort of police officer, writing tickets, others clearly work as the muscle of the place. They work under the control of the Archagent.
It is notable that lower ranking agents do not have sharp teeth; rather, they are "blunt like that of livestock".
