Not only is Statesman dead, but so is everyone related to him.

Well, the guy's wife died of old age sometime in the 1980's. Even if he was completely faithful to her until the end, he's had 25ish years of being a widower who's not only young looking (age 34 at the most since that's when he drank from the well) but way beyond being in his physical prime. He's the most famous man in the world and probably has women throwing themselves at him all the time. Even if most women are too fragile for him, there are plenty of superladies out there. There's bound to be a few that had some 'no strings' fun with him over the years. He might even have a regular relationship with someone that they've kept hidden to avoid publicity. So there's certainly the possibility of States having other children. Maybe lots of them and some that he doesn't even know about.

The devs have explicitly stated that Statesman is the one being removed from the game world, although this won't happen until Issue 22 due to implementation issues (and is more fitting for an Issue release anyway).

A good example is Praetoria - when you play the 1-20 content, the war hasn't started - the story builds up to the discovery of Tyrant's plans to invade Primal Earth.
Once you escape from Paretoria, you should next meet the loyalists AVs in the 45-50 range on Peregrine Island, only now, the invasion is about to happen, just s Statesman has disappeared, so you have to go find him and fight the Avs on the way.
Next comes the actual invasion at 50, with first the Apex TF, where Kings Row and Steel Canyon are attacked, then the Tin Mage TF, where we fight off the Praetorians in the Rogue Isles, the Vanguard base, and Peregrine Island, and then launch a counterattack to Neutropolis to knock out the invasion portals.
Mender Ramiel arrives from the future either just befoe the invaison, or as it starts, and Prometheus appears at the Ouroboros Citadel after we've taken out the invasion portals, but before we take the war to the loyalists on their own world. Around this time, Tyrant also empowers his henchpeople with some of his Incarnate power as he becomes more and more dependent on the Well.

That's where the Admiral Sutter TF messes things up a bit - it deals with the Paretorian invasion, but instead of being at 50, it's at 20-40, which means that players can learn about the invaison 1-20, fight the invasion 20-40, then learn the invasion is abotu to hapoen 45-50, then fight the invasion at 50

The Trials don't have any level related progress, as even the tougher ones don't require players to have a level shift to play them.
So while they can be played in any order, the correct sequence starts with the BAF, which isn't a major military target, but the discovery of Mother Mayhem's mindwashing plan to spread chaos in Praetoria and blame it on the Resistnce and Primal Earth means that it's something we have to deal with right away.

Once that's done we can turn our attention to a proper military target - Lambda Sector, where the newly empowered Marauder has been sent following events that happened in the 20-30 content in First Ward, when Dominatrix came up with a devious plan to make sure he'd be sent there by Tyrant, leaving her in complete charge of the Magisterium in Nova Praetoia.

After smashing this major loyalist supply depot, we then move onto the Keyes Island reactors, which not only power the invasion portals and the Warworks construction facilities, but also the sonic fences - and during the 20-30 First Ward content, we learnt that Tyrant and Anti-matter had used the sonic fences as a weapon to almost wipe out everything in First Ward, and with the war starting to turn against them, there's the danger they could try the same thing again in Praetoria City, or, as we find out durign the Trial, in his insane rage, Anti-matter sends the reactors into meltdown, which means that the sonic fences would lose their power and the city would be open to the Devouring Earth.

Once we defeat Anti-matter and secure the reactors, along with the security of the sonic fences and the ability to shut down any more invasion portals and slow down the construction of more Warworks, we then get a message from Vanessa DeVore, asking us for help, as she's learnt a big secret that could badly damage Tyrant's standing with the people of Praetoria.
Statesman sends along his new sidekick Desdemona, who in the lowerl level cotnent was still a rogue on the path to redmeption, to help us as we follow Vanessa's trail deep into the Underground, where we encounter an avatar of the Hamidon, which kills Vanessa.
Desdemona takes her mask, becoming the new leader of the Carnival of Light, and from the consciousness of Vanessa still attached to the mask, learns the secret that Vanessa had discovered - Tyrant had never defeated the Hamidon - instead, he'd made a deal with it, where it'd agree to stop attacking humans if Tyrant would make sure humans couldn't cause anymore damage to the world, which he did by creating his dictatorship to control them.

Now that we have this secret, we need to get it out to the people, so they can see how Tyrant has betrayed and lied to them, so we head for the TPN campus, where the loyalists are of course desperate to stop us broadcasting the truth.
Once we defeat them and let the people of Praetoria know what Tyrant's really like, we don't get the expected uprsinig - instead, the people stangely become even more loyal to Tyrant, and we soon find out why - Mother Mayhem has taken control of Penelope Yin, the daughter of Vanessa DeVore, and one of the msot powerful psychics in Praetoria, and using that psychic power along with her own, as well as an imporved version of the midnwashing plan from the BAF, has mindwashed the entire world, turning almost everyone into fanatical supporters of Tyrant.

We're unable to attack her asylum directly, because of the psychic protection wards all around it - but we manage to find an unguarded node that lets us into the Seer Network, where we can fight the mind of Mother Mayhem directly.
We eventually defeat her consciousness, freeing Penelope Yin, along with Aurora Borealis, whose body was being used by Mother Mayhem.
During the battle, we meet Metrononme, who has turned away from evil, and is now using the refitted body of Siege after we smashed it during the BAF raid, and we also discover that Calvin Scott was never married to Aurora Borealis as he'd claimed - it was part of his delusions as a mental patient at the asylum whre she ws treating him.
This revelation totally shatters Calvin, and he's left in no state to continue to lead the Resistance military struggle, with Penelope, Aurora and Desdemona coming together to take charge of the final stage of the war with Tyrant and the loyalists.

Though we CAN stand on it's roof to collect a day job badge.

Technically, that's before the MoM Trial as FW is 20-30
