Revolt

Every planet you Occupy will eventually Revolt from you (Permanent Planets do not revolt). When in your tributary you can check the Revolt Percentage of each individual planets as it increases. The revolt percentage will increase by an ammount every time your occupied planet tributes its creatures.

When your revolt percentage is in the Green, your planet is safe for now, but any revolt percentage in the red has a chance at revolting from you after the next tribute. You can Lock your planets to reduce the percentage or put it in the green for longer, the Planet That Have Many creatures rule is you get 12 hours per 10 turns lock, up to 50 turns.

You may also choose to Gold Lock your planet, in which your planet cannot be occupied by any other player, and will have its revolt percentage stuck at zero for a period of days, dependant upon the length of gold lock you choose.
