Babe, I Got a Ninja Problem

"oh, that's easy! it's because they're fundamentally Bad people who want to hurt others and choose their beliefs to justify that! :) hope this helps"

or

"they just don't have access to the same information we do. look at this person who was raised in a cult! don't you feel sorry for her?"

and like, yes, fine, some people were in fact raised in cults, but what i wish people would understand is that the bulk of it is just normal human flaws, like:

they want to believe stuff that makes them feel smart and cool and like they've figured everything out (you also do this)

they want to believe stuff that makes them feel like their emotions are justified and grounded in reality, and that the people they want to hurt deserve to be hurt (you also do this)

they form conclusions before they've processed all the relevant information, and cling to that first impression even when new info comes to light (you also do this)

they pick up beliefs from the people around them because they want to be liked and fit in, not because the beliefs are good or true (you also do this)

they come up with reasons that the stuff that benefits them (and the people they like and identify with) is actually overwhelmingly best for everyone and obviously the right thing to do (you also do this)

they pay more attention to stuff that supports what they already believe and avoid looking in places that might show them otherwise (you also do this)

they listen to people who talk like 'one of them' and ignore others (you also do this)

they come up with reasons to dismiss people with conflicting viewpoints as obviously in bad faith or ignorant or a shill or evil (you also do this)

they fail to take their own beliefs seriously sometimes, and take their beliefs way too seriously other times, in a selective way that lets them do the things they already wanted to do (you also do this)

the very ways they construct the ideas of 'knowledge' and 'wisdom' and 'belief' and 'understanding' are biased so that what they don't want to believe comes under lots of scrutiny and what they do want to believe receives less (you also do this)

you, dear reader, are presumably right about everything and were correct to die on every hill you've ever died on, but the difference between you and someone who's wrong about important stuff doesn't look like "well they're inherently evil and i'm not", it probably looks like a combination of:

natural environment (they would have been exposed to different information than you regardless of their choices)

being in the right place at the right time (your particular profile of flaws and virtues happened to be what was needed to lead you to the right conclusions, they had the opposite experience)

random luck (you doubled down on what felt right to believe but wasn't, but it turned out to be inconsequential, or even right for different reasons, while they doubled down on what turned out to be a horrible mistake distorting their entire worldview)

you do less of the things in the previous list, and over time the difference between you and them adds up

and, look, i also do these things. the nicest and most thoughtful people i've ever met do these things. if you meet someone who never does any of these things, i dunno, give them a fucking medal or something.

First, Brennan uses Hannan as an antagonistic force toward the Seekers he unifies them by standing against both Occtis and Vaelus. He also provides contrast to the more measured and peaceful Druids we've seen thus far. He provides a counterpoint to Vaelus, the only other Elf we've seen in the campaign, and forces her to reveal more about her position regarding the Shaper's War by defending it.

As his relationship with Vaelus develops, we get more nuanced glimpses of what Elvish life is actually like, the full weight of Sylandri's hold of her creations, and Vaelus admits who she actual has been missing and grieving all these years; not Sylandri, but her family. Admitting this lets us understand the sacrifice she makes when she chooses to put her family aside, to break the Stone of Nightsong and help the Rungjani dead find peace.

And of course, when Hannan learns of Mara's capture he flies to Obrimus Manor to help her. There, he does not barge in to search, instead he starts to counter the Undead. This is extremely important support for Thimble. The magical darkness dissipates, her search difficulty decreases significantly, and the undead threat is lessened greatly. I feel confident in saying that Thimble would not have succeeded without this intervention, but critically, he supports Thimble's success without swooping in to make it his own.

With this support, she is able to finish off the Undead Monstrosity that was Raimond Davinos. Now Teor's death is not in vain because she heroically finished the work he had started. Together, they rid the world of a great evil while freeing Raimond's spirit and recovering his blade.

Thimble is able to recover the Pridesires. Their spirits and bodies cannot be harnessed by the Tachonises. She recovers the Royce Bracers and the Einfassen ax, which could have complicated things had they been discovered in the crypt. She also finds valuable information throughout her search, learning where the Gnomish statues were taken and information on the tenebral ship. Hannan facilitates all of this as he holds the darkness and the dead at bay.

The last important thing Hannan does is to die.

And this is very important, narratively.

Primus Tachonis has been bested by the work of the Magpies. We've seen him threatened by the Einfasen and condescended to by Yanessa Halovar. Why should we be threatened by him? Maybe he's just prideful and sloppy. Maybe he's careless and stupid. Maybe he's actually not that frightening.

And then he kills Hannan without a second thought, and we see the truth that Brennan has been nudging us toward since the beginning.

Primus is not stupid or short-sighted, he is panicking.

He knows things we do not. He knows something is coming, and the full wrath of the Druids that may come in a handful of months doesn't matter, because there are larger forces at play. So yes, the Einfasen and the Cormorays are deeply powerful and the Halovar's have power and influence as well as cunning and poise the others seem to lack.

Even so, Primus Tachonis is the most dangerous threat right now, because he is desperate. In his mind, he has nothing to lose. The murder of Hannan proves this.

Sometimes the cost of a great story is the loss of a great character.
