Basic mechanics

• Player joins/forms an alliance or invites other factions to it using the "special options" menu when docked at a market.
  • Player must not have a commission (otherwise the commissioning faction handles all alliance matters).
• When a member of an alliance starts a war with or makes peace with another faction, the alliance members vote on whether to do the same. If the player is an alliance member, a popup dialog will ask player for their vote.
• Purchases can be made from the military market of a faction allied with the player, or with the player's commissioning faction.
• The player cannot hold a commission and have their personal faction be in an alliance at the same time.

Alliance properties

• Each alliance has an alignment: Corporate, Technocratic, Militarist, Diplomatic or Ideological.
• Each faction can have one or more alignments (values can be negative).
• To form a new alliance, both candidate members must be at least friendly and have at least one of their alignments sum up to >=1 point.
  • Alignment is not checked for player-formed alliances.
• To join an existing alliance, candidate must be at least friendly with all its current members, and their value for the alliance’s alignment must be >=0.
  • For player inviting someone to an alliance, only the relations between player and the faction are considered.
• Alignment effects can be disabled in exerelin_config.json.
• To remain in an alliance, a member must at least average welcoming with all other members, and not hostile to any of them.
• Every ~30 days, for an NPC faction not in an alliance:
  • First check if can form alliance with any other faction.
  • If can, and we pass the RNG check, form alliance.
  • Else, check every existing alliance and see if can join (also has RNG check).
• Pirates cannot join alliances.
