 ### Welcome to Maraxsis
 
 Let me introduce this pristine, submerged world. Far away from the sun, this planet paradoxically maintains a comfortable temperature through a runaway greenhouse effect. 
 
-Preliminary surface scans show an average temperature of 101°F (38,33°c). It's not too hot and not too cold, the perfect Goldilocks zone for liquid water. Maybe even too perfect...

 Maraxsis is 100% covered by deep ocean. There is no land on the entire planet meaning you'll have to invest in aquatic technologies such as submarines, torpedos, hydro plants, and submerged pressure domes. In terms of progression, Maraxsis is unlocked at the same point as Aquilo. This means the mod can be seamlessly added to a finished Space Age save.
 
+Maraxsis is designed to take approximately fifteen hours to complete. There is also huge megabasing potential for those who would rather stay for longer.
