Landsraad
Many of the day to day rulings of the Imperium are made by the Landsraad High Council. All decisions must be ratified by the Emperor, however.
Due to the ongoing War of Assassins on Arrakis, the Landsraad votes on a weekly decree that could tip the scales in either side's favor.
Player Guilds aligned with either House Atreides or House Harkonnen compete to win the favor of the Landsraad for their respective patron House.
Sysselraad
The playable faction that is able to secure a Sysselraad[1] will win the vote for that Landsraad Term.
A Sysselraad is secured on the Landsraad board under one of the following conditions:
- Five Houses secured in a row, either horizontally, vertically or diagonally.
- More Houses secured than the opposing faction by the start of the Voting Session
Players who are Guild Leaders aligned with the winning faction will be able to vote for one out of three Decrees to put into server-wide effect for the next week.
Weekly Rewards
Every week when the new Landsraad Term begins, aligned-Guilds compete with the opposite side to accumulate standing with each House. The first side that reaches 70,000 
Landsraad Contribution will earn the vote of that House during that term.
On top of that, players can earn individual, tiered rewards from each House every term, by completing Landsraad Missions on behalf of a House.
Each House will have 5 tiers of rewards, which are randomly rotated, and the thresholds are as follows:
- Level 1 - 700
- Level 2 - 3,500
- Level 3 - 7,000
- Level 4 - 10,500
- Level 5 - 14,000
These rewards will accumulate across Landsraad Terms, and can be claimed from the corresponding House Representative at any time.
Landsraad Missions
In Chapter 3, Landsraad Missions were added, expanding the PvE endgame and replacing the previous type of Landsraad tasks, such as missions to kill a certain number of enemies, or delivering resources or vehicles to the faction Quartermaster. At any given time, each Landsraad bloc has three Landsraad Missions available for players to choose from, which can be completed in service of any House in that bloc, provided the House is currently revealed on the Landsraad board.
Decrees
The Landsraad provide powerful decrees which vary from providing unique vendors to altering how action is dictated in the Deep Desert.
Every week, guild leaders with sufficient Guild Voting power, gained through Landsraad Missions, can put those votes towards a specific Decree; The decree will last until the end of the Landsraad Session, just before it's on recession, shortly before the Deep Desert weekly reset.
The Guild leader must vote on one-of-three decrees which are randomized per week.
