The planetariums are smaller representations of the 
Retroverse designed to help newer players become 
familiar with the worlds around them.  Planetariums 
can be found in Edon (Sosel), Igneous (Crypt), 
Keystone (Welstar), Sauronan (Wysoom), and 
Scarrowfell (Perdow).
    
Inside each planetarium you will find a model of the 
Retroverse, complete with the six worlds following 
their orbits around the sun. Once found (use "map" 
to help navigate the planetarium), each planet can 
be asked about itself to obtain a list of topics 
by typing "ask  about " (such as 
ask raji about raji). It can then be asked for 
more details by typing "ask  about ."
    
Each planet also has a full map of its outerworld. 
To read the map, use the commands "read map 
legend" or "read map " (where level is most 
commonly an integer ranging from -5 to 5).
