Idea for the last planet in the system.



Ptolomea: Ptolomea is a barren rocky desert planet close to the systems sun, effectively a arid sinkhole world. It has the longest rotation period of any planet in the system and rotates in the opposite direction to most other planets. It has no natural satellites. The ground is covered in extensive volcanism, and the sulfur in the atmosphere is due to the planets volcanoes and their periodic eruptions. It is these constant eruptions that has allowed the mineral rich deposits to be shifted further to the planets surface making iron easy to mine. Surface water makes up only 0.9% of the planet. Sinkholes on Ptolomea are a common geological feature that appear in areas where the rock below the surface of the land is made from substances like salt beds, limestone, carbonate rock that can be dissolved by ground water flowing through them. This rock can also be weakened by acidic rain. Many of the most massive mining facilities are in fact built into these sinkholes and reinforced with steel and intertwining arch bridges. This has proven necessary due to the powerful [i]flay storms[/i] that run across the planets surface. The winds here are so strong they throw small stones into the air and this combined with the winds can flay skin from bones and even tear apart thin metal.
