The Vort

"In a corner of a faraway galaxy lies THE VORT, a world bisected by a raging vortex at each pole. For the Aggregated Planets' Cultural Union, it's a source of enormous energy and ripe for mining. The alien natives, however, will protect it at all costs - and the Vort's unique electromagneticism means nothing electric will work..."

The Vort was a comic strip by Simon Spurrier and D'Israeli published in 2000 AD progs 1589 to 1596 (pictured). The twist at the end to which this cover refers is that one of the main characters turns out to be the eponymous protagonist of Lobster Random, who is a mutilated sociopathic torturer.
