What Happens At The End Of Eisenhorn: The Omnibus?

The ending of 'Eisenhorn: The Omnibus' is one of those moments that leaves you staring at the page for a good while, just processing everything. Gregor Eisenhorn’s journey throughout the trilogy is this incredible descent into moral ambiguity, where the lines between righteousness and heresy blur more and more with each decision he makes. By the final act, he’s no longer the pure, by-the-book Inquisitor we first met. Instead, he’s become something far more complex—willing to cross lines he once would’ve deemed unthinkable, all in the name of combating chaos. The climax sees him facing off against Pontius Glaw, this ancient, utterly ruthless enemy who’s been a thorn in his side for ages. The showdown is brutal, personal, and loaded with the weight of everything Eisenhorn has lost along the way.

What really sticks with me, though, is the aftermath. Eisenhorn wins, but at what cost? He’s forced to rely on forbidden knowledge and even daemonic pacts to pull it off, things that would’ve horrified him earlier in his career. The final scenes are haunting because they don’t offer easy answers. He’s triumphant, but he’s also undeniably compromised, and you’re left wondering whether the ends truly justified the means. The way Dan Abnett writes it, you can almost feel Eisenhorn’s internal conflict—the pride in his victory mixed with this creeping dread about what he’s becoming. It’s a masterclass in showing how war, even against the darkest evils, can corrode the soul. I still get chills thinking about that last line, where Eisenhorn acknowledges he’s now something 'other' than what he was. It’s the kind of ending that lingers, making you question everything right alongside him.
