Contents hide Who is Leandros in the original game Leandros in Space Marine 2 and The Stain of Suspicion

This page contains story spoilers related to Space Marine 1 and Space Marine 2. It is advised you read the page with caution. We summarise the events of Space Marine 1 to better explain who Leandros is in Space Marine 2. There’s some meta-analysis and how it relates to character development to help piece together what you might have missed or forgotten due to its relative unimportance at the time.

Who is Leandros in the original game

Leandros is one of the young Space Marines who works alongside Captain Titus in Space Marine 1. Leandros is very much interested in his codex doctrine and worships it and follows it to the letter. Captain Titus, on the other hand, is more of the opinion that it’s a set of guidelines to follow. In Titus’ opinion, the best Astartes are the ones who can adapt the Codex, rather than follow it blindly.

This is a pain point of the relationship between Titus and Leandros. It’s worsened by the Chaos artifact, which we now know as the Aurora project. It’s a suspicious Chaos artifact retrieved by the Ultramarines . But, to retrieve it, Titus had to physicallyy handle the artifact, which gave off incredibly powerful warp energy that would be enough to kill most mortals. But, Titus survived. We see Titus having some connection to the Immaterium through Chapter 2 via the resistance to the Thousand Sons and the maddening effects of the warp.

The combination of the natural differences between codex enforcement and the interaction with the Chaos artifact raises too many suspicions. Leandros reports Titus to the Inquisition, the Imperium institution for rooting out heresy amongst its population and forces. It’s another reason why the Chaplain has concerns early on in the Space Marine 2 campaign.

Gadriel’s storyline somewhat mirrors Leandros’ and it’s partially Leandros’ fault. Captured by VideoGamer.

Leandros in Space Marine 2 and The Stain of Suspicion

At the end of the Space Marine 2 campaign, we find out that Leandros is the Chaplain. This makes a lot of sense based on character development in both games. The Chaplain’s personality is very dogmatic to the chapter and Ultramarines. This behaviour helps to identify why the Chaplain is always suspicious of Titus and his squad. The Chaplain says it himself in the prologue and epilogue:

The stain of suspicion never goes away. 

Interestingly, we see a mirror of Leandros in Gadriel due to this stain. Gadriel’s is somewhat suspicious of Titus. Suspicion builds up as the campaign plays out. Titus hides conceals his background, the darker details of the Deathwatch, and more from his squad. This is due to the advice the Chaplain gives to Titus after he awakes from surviving his biological enhancement into a Primaris marine. Bear in mind that we do not know the Chaplain is Leandros at this point. We only meet the Chaplain for the first time at the end of the prologue.

Tensions hit a climax with the Navigators in the temple during the campaign. The navigator warns of the Chaos interference – sending messages and the extreme risks warp communication brings. Consequently, the navigator gets possessed and accuses Titus of Heresy. Gadriel is happy to believe it is true due to the Stain of Suspicion. The only thing saving Titus at that point is Chairon figuring out that the mark of Chaos is involved. It puts Gadrial in his place and he begins to trust Titus more. Something that Leandros never got.

Evidence of this reveals itself during the summon to see the Chaplain before mission 6. The Chaplain is somewhat disappointed in Gadriel. He also mentions he won’t hesitate if the Stain of Suspicion once again shows itself to be true.

This Stain of Suspicion is a convenient for Leandors and his role as Chaplain. Yet Gadriel eventually comes round to Titus after he was nearly tricked by the Thousand Son’s trickery and deceit. It adds a little more to Leandros’ character and his inability to let what he saw in the first game go.

Wherever Titus is off to, he’s going with the Chapter Master and the Chaplain. That’s going to create some interesting story developments. The Chapter Master hates that Titus was sent to the Inquisition and the Deathwatch, per the conversations on the campaign’s mission 6. Leandros was responsible for getting him sent there in the first place. It’s interesting to consider how the Stain of Suspicion will follow Titus this time, though he is surrounded by brothers who trust him, except for the Chaplain. If the storyline continues, it’s likely that Leandros will have further involvement with Titus.
