Relation bonus

When interacting with other space faring creatures during the space age. You will have a relationship with them. You can improve the relation or worsen it by certain actions or even simply by what you did and chose in your creatures previous phases.

You can get any of the following modifiers up to a given maximum, meaning when you are at the maximum modifier for it then the relation will not improve or worsen even if you continue repeating it.

A second thing is most relation modifiers will return to default over time. So you will have to keep active for some of them to keep them up. Only a few are static and will remain over time. Unless you start a war with them and sign peace later. In which case you can loose the uplifted bonus for example.

All modifiers from the different groups are then added up and the resulting value is your total relation bonus to them.

Relation Bonus Reset
There are but a few ways to completely reset the Relation Bonus back to initial values.
 * Ending a war by signing a peace treaty, the one you buy from your opponent empire for cash.
 * Bard song

Ending it by signing a peace treaty will remove any and all positive and negative bonuses apart from the ones that are natural for the race, like 'We distrust strangers'. 'Even Allied with Grox', 'Breaking the Galactic Code', all is forgiven.

Effect
Based on your relation you can have hostilities or war, set up a traderoute (blue face) an alliance (green face). Also the price to repair and recharge is based on relation. N.B. The trade prices are unaffected however.

Grox
Relation with The Grox is different from all other races and you will receive lesser or even reversed relation bonuses with them.
