HL Universe

The HL Universe is the main universe where the Half-Life series is set, starting with the original Half-Life (1998).

Another timeline branched off from this one in the form of the C17 Universe.

Nearly twelve years since its last appearance, Toby Purnell found himself in this universe. The characters inhabiting it seemed to be stuck in a loophole with little development happening (such as City 17 still being destroyed, and most of the earth being a barren wasteland). The only change was that the resistance appeared to be in control of the Combine forces of earth, and Alyx Vance acted as the earth's administrator, but had developed into a cold individual due to the death of her father Eli Vance. Gordon Freeman lived in isolation at a cabin in the outlands, depressed over the fact he was unable to avenge Eli's death and failed to discover the Borealis, and also longed for the appearance of his "friend" G-Man, who had disappeared twelve years prior.

Toby's evil counterpart Herr Purnell overthrew Alyx from her position of earth administrator and established his own ruthless earth government very similar to the Combine. He invited "friends" over from other worlds such as the C17 Universe and G Universe, before subsequently destroying those worlds, feeling that he was back at "home" in the HL Universe. He later used it as his own personal playground for his followers to wreck havoc and dominate over the enslaved population.
