Aggro is one of Tellur's two moons. Between it and Aeris, Aggro is the smaller of the two at a radius of 4,000 kilometers, and it orbits around its counterpart. From the surface of Tellur, Aggro appears to be a brownish-red color. It contains no discernable surface features aside from mottling to the naked eye, and observation by telescope reveals that its surface is obscured by thick clouds. Astronomers can see regions that glow with red light and occasional flashes of white light, suggestive of activity below the clouds.
In some places on Tellur, there are ancient portals that lead to the surface of Aggro. Travellers must prepare themselves with some form of protection, however, as the atmosphere is too hot, thin, and toxic to support life. Those who have dared to venture there describe it as an ashen, volcanic wasteland, plagued by constant volcanic activity, earthquakes, and acidic lightning storms. This activity is believed to be due to opposing tidal forces between Aeris and Tellur, supported by the fact that the earthquakes are more severe when Aggro's orbit brings it closer to Tellur.
Sometimes, Aggro can pose a danger to Aeris and Tellur. Volcanic eruptions can sometimes result in verneshot➚, which falls to Aeris or Tellur as a meteor. Such events are thankfully rare, however. Usually, any debris that escapes from Aggro's gravity is small enough that it burns up during atmospheric entry before it can do any damage.
