Kinnison and VanBuskirk, in one of the boats, were forced to land upon the planet Delgon, where they joined forces with Worsel--later to become Lensman Worsel--a winged, reptilian native of a neighboring planet, Velantia. The three destroyed a number of the Overlords of Delgon, a sadistic race of monsters who preyed upon the other races of their solar system by sheer power of mind. Worsel accompanied the Patrolmen to Velantia, where all the resources of the planet were devoted to preparing defenses against the expected Boskonian attack. Several others of the _Brittania's_ lifeboats reached Velantia, called by Worsel's prodigious mind working through Kinnison's ego and Lens. Kinnison finally succeeded in tapping a communicator beam, thus getting one line upon Helmuth, who "spoke for Boskone"--it was supposed then that Helmuth actually was Boskone instead of a comparatively unimportant Director of Operations--and upon his Grand Base. The Boskonians attacked Velantia and six of their vessels were captured. In these ships, manned by Velantian crews, the Tellurians set out for Earth and the Prime Base of the Galactic Patrol. Kinnison's Bergenholm, the generator of the force which makes inertialess--"free," in space parlance--flight possible, broke down, wherefore he had to land upon the planet Trenco for repairs. Trenco, the tempestuous, billiard ball-smooth planet where it rains forty-seven feet and five inches every night and where the wind blows eight hundred miles an hour. Trenco, the world upon which is produced thionite, the deadliest and most potent of all habit-forming drugs. Trenco, the Mecca of all the "zwilniks"--members of the Boskonian drug ring; sometimes loosely applied to any Boskonian--of the Galaxy. Trenco, whose weirdly charged ether and atmosphere so distort beams and vision that it can be policed only by such beings as the Rigellians, who possess the sense of perception instead of sight and hearing! Lensman Tregonsee, of Rigel IV, then in command of the Patrol's wandering base upon Trenco, furnished Kinnison a new Bergenholm and he again set out for Tellus. Meanwhile Helmuth, the Boskonian commander, had deduced that some one particular Lensman was back of all his setbacks; and that the Lens, a complete enigma to the Boskonians, was in some way connected with Arisia. That planet had always been dreaded and shunned by all spacemen. No one would ever say why, but no being who had ever approached that planet uninvited could be compelled, even by threat of death, to go near it again.
