Surface Features:
Ici is the second, smaller moon of Blalo, but still quite massive in comparison. The dominant feature across the landscape is smooth, dusty glaciers. The majority of the crust is an ice sheet composed of frozen water and carbon dioxide with an average thickness of 40 km. The surface itself is coated in a fine silicon dust similar to finely grained sand. This gives the moon a light grey hue, due the mixture of ice reflecting light, and the dust absorbing it. The surface is very uniform, with only a few hills and canyons disturbing the nearly flat landscape.

Internal Structure:
It is speculated that Ici is geologically dead, that is the entire moon is solid with no liquid core or tectonic activity present. The core is thought to be a medium metal/rock sphere no larger than 850 km in diameter. The mantle is a mixture of liquid water pockets and solid rock and ice, with the liquid water pockets slowly freezing up and shrinking. Tiny quakes have been detected around the moon, only strong enough to be detected by seismographs. They are most likely the result of impacts from meteorites and ice shifting within the crust.

Atmosphere:
Ici has no atmosphere to speak of. A thin, tedious layer of oxygen and argon less than a meter thick floats across the surface, although at a pressure less than a thousandth of a bar. So in practice, Ici’s surface is entirely exposed to the vacuum of space around it.

Orbit and rotation:
Ici has a very stable orbit around Blalo, and as with most moons, it rotates at the same rate at which it orbits, always showing the same side to Blalo throughout its orbit.
