Joralla, considered to be the primary planet of its star system, had breathable air and circled its star once every 310 local days. It was a tropical jungle world that Jaska bathed in crimson light.
Behind the scenes
Jaska was first mentioned in Planets of the Galaxy, Volume One, a 1991 sourcebook for West End Games' Star Wars: The Roleplaying Game. The 2009 reference book The Essential Atlas placed the Joralla system, and therefore Jaska, in grid square L-17.
