Input: The story of the rise of politician Willie Stark from a rural county seat to the governor's mansion is depicted in the film. He goes into politics, railing against the corruptly run county government, but loses his race for county treasurer, in the face of unfair obstacles placed by the local machine. Stark teaches himself law, and as a lawyer, continues to fight the local establishment, championing the local people and gaining popularity. He eventually rises to become a candidate for governor, narrowly losing his first race, then winning on his second attempt. Along the way he loses his innocence and becomes as corrupt as the politicians he once fought against. When his son becomes paralyzed following a drunk driving accident that kills a female passenger, Stark's world starts to unravel and he discovers that not everyone can be bought off. The story has a complex series of relationships. All is seen through the eyes of the journalist, Jack Burden, who admires Stark and even when disillusioned still sticks by him. Stark's campaign assistant, Sadie is clearly in love with Stark and wants him to leave his wife, Lucy. Meanwhile, Stark philanders and gets involved with many women, taking Jack's own girlfriend, Anne Stanton, as his mistress. When Stark's reputation is brought into disrepute by Judge Stanton (Anne's uncle), he seeks to blacken the judge's name. When Jack finds evidence of the judge's possible wrongdoing, a quarter century earlier, he hides it from Stark. Anne gives the evidence to Stark, who uses it against her uncle, who immediately commits suicide. Anne seems to forgive Stark, but her brother, the surgeon who helped save Stark's son's life after the car crash, cannot. The doctor eventually assassinates Stark after Stark wins an impeachment investigation. The doctor in turn is shot down by Sugar Boy, Stark's fawning assistant. The main plot is a thinly disguised version of the rise of real-life 1930s Louisiana Governor, Huey Long, Long's efforts to blacken the name of Judge Benjamin Pavy, and Long's assassination by the Judge's son-in-law (compared to nephew, as in the film), Dr. Carl Weiss.

Now complete the following example -
Input: On the hot, humid ocean world of Xecho Dane Thorson has just finished his part in preparing the Free Trader (i.e. tramp freighter) Solar Queen to begin her run on an interstellar mail route. While waiting for the ship they are to relieve on the route, Dane, Captain Jellico, and Medic Craig Tau are invited to visit Xecho's sister planet, Khatka, by Chief Ranger Kort Asaki. A jungle world originally settled thousands of years before by native-African refugees from one of Earth's atomic wars, Khatka is a safari world, essentially a giant hunting ground where big-game hunters come to try their skill against large, dangerous animals. On Khatka the three starmen discover that Ranger Asaki is being undermined by a witch doctor named Lumbrilo. During a ceremony in which Lumbrilo has disguised himself as the local version of a lion, Medic Tau, who has studied magic on many worlds, conjures the image of an elephant, thereby earning Lumbrilo's enmity. On a visit to see Zoboru, a new, no-kill preserve, the three starmen, Ranger Asaki, and the flitter pilot are stranded in the jungle when their flitter crashes. The men must walk back to their base while avoiding encounters with Khatka's dangerous fauna. One such encounter tells them that they are being tracked and herded by Lumbrilo. In a deadly swamp the men come to a camp occupied by a small team of poachers. There Tau confronts Lumbrilo, turns his magic back on him, and sends him screaming into the jungle, thereby solving Ranger Asaki's problem. Captain Jellico and his men then return to the Solar Queen for what they hope will be a nice quiet mail run. 
Question: Whom invites the ships crew to Khatha?
Output: 


Output: Chief Ranger Kort Asaki.
