Pale and large, Tylo fights for the spotlight with Laythe. As an arid world, there is little to look forward to when taken at face value. But in Jool's influence, there may be more than meets the eye.

In a stable universe, this moon cannot keep its reputation as a gravity bully, and so, bows out and becomes a small world and 3rd place among the large worlds here (Jool, Laythe and itself). Rather than become just another unappealing, big brown orb, Tylo exercises the privilege to hold an atmosphere and some of the biggest craters ever seen in the JNSQ system. Other susprises may be found but are yet to be applied.
