Umbriel

Umbriel

Umbriel is the third-largest moon of Uranus, distinguished by its dark, heavily cratered surface. In Terra Invicta, this ancient and mysterious moon offers several habitation opportunities in the distant Uranian system.

Mining Sites

Notes:

• Negative values are not a bug, the game actually sets the median to a negative value to make it incredibly unlikely for the site to have a positive mine output. But note that the actual mined amount cannot actually be negative.
• Blank values indicate that the site can never produce this resource. In contrast, 0 indicates that there is still up to 50% chance for the site to produce the resource.
• Values shown do not take into account the final capping of the Noble Metals output to just 1/2 or 1/3 of the Base Metals output.
• Top 50% Mean is the average value of the top 50% of possible rolls. It is also a much looser estimate than the median because it cannot handle edge cases such as where the mininum value is too close to the median value.

Strategic Value

Umbriel's 4 habitation sites provide significant settlement potential in the Uranian system. Positioned in the middle orbital region, Umbriel serves as an excellent relay point.

Human expansion to the Uranian system often prompts a violent Alien response.
