Moirose
The Empire of Moirose is an intergalactic evil empire whose hold on the universe is always expanding. Planets under Moirose's rule are incredibly varied- as Moirosean culture and invasion practices involve preserving the local culture- and the empire makes its bountiful riches by using that uniqueness to draw in tourists.
Moirose is known for three things- The numerous "seedy underbelly" type locations on its many planets, a love of indulgence inherit to the culture, and their incredibly advanced technology. Moirosean technology- both domestic and military- is considered top tier across space, and is one of their premier exports.
Moirosean invasion nearly always begins with an invitation- a planet, seeking shelter from another force or aid during an apocalyptic crisis, will reach out to the Empire and ask to be taken in. Following that, Moirose will arrange some mock battles before officially claiming the planet as its own, all the while attending to the problem that caused the invasion.
Moirose is primarily populated by the Greys, a species known for their large eyes and frequent human contact.
The planet Hoplite, home to the insectoid, lagomorphic Hoplite people. Hoplite culture is incredibly combat-centered, with more peaceful moments punctuated with the building and maintenance of giant mechs, where the boldest fighter in each generation sees a mech passed down to them and personalized to their tastes. Their cultural acceptance of bloody battle and what most consider crime means Hoplites are a healthy amount of the galaxy's pirate population.
A much less cosmically known aspect of Hoplite culture, however, is music. Hoplites cannot understand others properly without some sort of musical experience shared between them- thus, ballads of victory and triumph are considered as valuable as golden-weaved tapestries, and Hoplite history is almost entirely passed down orally by song. Silent or musicless places are considered completely taboo on Hoplite, even in places where that silence facilitates necessary secrecy. While what style of music one plays to establish proper communication varies from person to person, seen as individual expression rather than ironclad cultural identity, it's common for allies in battle to harmonize by sharing their musical tastes between one another.
Hoplite is one of the core planets in the Moirosean Empire- many Moirosean ships see Hoplite captains and pilots. Despite this, pirates from Hoplite do not themselves act as privateers, and will often raid Moirosean cruise shuttles just as often as any other collective's vessels.
Also known as Moirose Prime- the origin planet of Moirose, known as the Dark Heart of the Galaxy. Casinos, coliseums, brothels, malls- you name an indulgence and Greizar has you covered. Greizar's primary species- the Greys- originate here.
The seat of power for the Moirosean Empire- Serves multipurposefully as a home and workspace for the ruling parties of the Empire, a tourist attraction, the empire's most popular Casino/Resort/Arcade/Concert and Convention Hall/Mall/Restaurant Hub.
