Outsider!

where you become the next Defender and cleanse Altgarten

you cut down Eddora

you still get blown up by the stick grenade even AFTER killing Eichlan and seeing his journal explain how it works and what it does. (I suspect you'll get killed by the sulfuric acid in the same way as well, but I haven't been interested in wasting the rare high-rolled characters capable of putting down that abomination just to test this.

Morrigan

he can still show up decades later when you search for the defender. Incredibly, according to the comments here, the game recognizes if you fled from him, but not if you actually killed him.

the werewolf in the valley

the zombie servant is such an afterthought. Wood elves do not care about its presence, and neither do the castle guards at Perrereich, apparently. Worse, it somehow ends up in that psychic battle from the past (and basically always gets killed if it makes it that far). Coming from the skeleton tooth of A Princess of Zamarra, the contrast is shocking.

neither the elves, nor the father & daughter next to the unicorn, nor the guards at Arielburg (or something. Just remembered that it's certainly not Perrereich, as that is Prince's land) nor any other encounter takes note of that zombie. It would have been cool if while approaching the Lasombra drug den, attempting stealth forced you to leave the zombie outside, and he wouldn't have joined the fight until a few turns in.

no combination of past actions seems to have any bearing on that shadow elf, with the choice to approach her in different ways apparently completely meaningless.

when doing that contract, you get a reference to footpads attacking you in 632, where you are testing your luck, regardless of whether or not that actually happened.

lead-up to the main endings, at 126, shouldn't it be "burn down the mansion" rather than "fire the mansion"?

Eddora getting butchered

Simply put, I don't believe in their cringe romance. Aria's insistence on how he totally will never ever sleep with another woman again grew grating soon enough, and absolutely nothing about Eddora once she actually shows up makes this look remotely warranted. The whole speech about finding the beauty in sunrises is funny when she slits her own throat five seconds after you pick what should have been completely predictable response from her block-headed beloved. (Her being supposedly 93 at that point makes this even weirder.) The more canonical alternative is possibly the worst scene in this gamebook. It's incredibly dumb, same as the endgame it exists to enable. Simply throwing all of those assassins at the Prince as cannon fodder would have bypassed the whole prison bullshit with all those instakill forks and removed the whole basis for "third-best ending" to exist.

Kandron finds out that the two strongest assassins in the world, and those with the best odds of killing him, have just broken out, and his reaction is...to immediately teleport HIMSELF in front of them, right before throwing away years, if not decades, of alliance-building work on a temper tantrum, and threatening the guy he had then turned his back to? As opposed to, you know, keeping quiet and teleporting some more guards/warriors into the dungeon first (the same guards who had potentially already managed to bring down both Aria and Eddora after all) and only then joining the fray?

Aria and Eddora to even attack the Prince in the first place! The Prince wants to destroy assassins in general, and Aria opposed him because being an assassin was all that he had left outside of Eddora. But after he himself had disbanded his own guild on a whim, there is literally nothing keeping him (let alone Eddora) in Altgarten anymore! In fact, in both endings, they immediately leave the city anyway, never to return! Yeah, perhaps the Prince would have tried bringing them back into the city to get executed for his bow-wrapped victory proceedings anyway, but not only do they not know of his plans at this stage, they obviously have way better chances against inferior assassins or dark elf raiding parties or whatever then against hordes of guards on their home turf. The fact that in the canon endings, you let a Necromancer who had butchered untold number of people live and learnt from him for months, even though you knew he wasn't even your father, also gives lie to the idea either of you cared about what the continued vampiric rule would do to the city.

the army of Arielburg, arriving soon after you burn down the mansion at night, apparently fails to do anything about your execution the morning after if you fail to break out. I certainly don't get how come they do not show up in the YEARS which elapse between Eddora's suicide and Aria's own after he says no to her. Further, if the Count was able to find out where Aria really was in Altgarten, how come Eddora does not find Aria in Arielburg in the ending where he never returns to the assassination business and assumes the role of the heir right after saving Alfred from a boar? She claims she left in the first place because she was afraid of Aria turning to darkness: if she is not lying, then how does him becoming a count not allay her fears?

That whole conversation in the jail cell, with Aria screaming at Eddora that the dark elven eschatology is wrong and there's not going to be anything after death, is a blatant example of what TVTropes calls Author Tract. It's not that I would disagree in the real world: it's that this position makes ABSOLUTELY NO SENSE in Titan - and there 0% chance Aria could say that with a straight face if he faced the wraiths in the tomb, or if he had summoned his mother's spirit.

a moron who killed his apparently most promising follower for mentally doubting the value of the organization he himself then outright disbanded on a whim HOURS later, before their own greatest fight, and the spouse who murdered two random whores FOR NO REAL REASON right before their meeting would do anything good for Arielburg, Right-Hand Side (which apparently failed to restrain Aria in any way, since there is zero difference between his behaviour if he turned away from the Defender's path and if he never met the Defender) or not. Arielburg unbelievably transforming itself from a land "shackled in chains of poverty", with one stone building in the realm, to "one of the most prosperous kingdoms" in a few...years? since you have saved Alfred is a cherry on top. Not to mention that getting there REQUIRES Aria to allow a Necromancer who did unspeakable crimes to countless people of his city to keep doing that indefinitely (right before participating in it for months, of course) - not something I see a remotely worthwhile leader doing.

If they do, my impression of the Grand Councillor shoots all the way up from "Complicated" to "Actually pretty good".

When Salome says she might have to Embrace Fiorentino, doesn't this directly contradict Prince's claim that he has the sole control over Embrace?

The one where you accept becoming Alfred's heir immediately, and the one where you defeat the ghost you irresponsibly summoned and forgot about but lose Eddora to poor dice rolls

Even if we assume the Prince, Councillor, et al. weren't sure of the full extent of the assassins' activities at Pied Cow (which seems unlikely when considering all the rich kids showing up, there would have been no doubt left by the time they got to Jorah. Once Aria killed the Councillor, the Watch would have had Pied Cow surrounded the next day/night (depending on whether the Prince himself and perhaps some other nobility decide to show up or not and probably just burnt the whole thing down if they didn't feel like taking losses.

Aria's first order after taking charge would have had to be to decamp ASAP, and then either somehow try to establish a new meeting place which their clients would still trust and wouldn't have gotten raided as soon as the Watch captures someone alive or (much more likely) just throw literally everyone who didn't get cold feet after losing the Pied Cow at the Prince in revenge and hope for the best.

At that point, you could work Eddora back in as well - perhaps she just coincidentally returns the same night (same coincidence as the dark elf trio showing up at the same time you disband the Guild) or perhaps she was already captured by Kandron and her knowledge of Aria and the underworld was passed on to the Prince and her existence used as a bargaining chip. (In fact, it would be more interesting if the Grand Councillor lied about where he got the information from, so that even if he loses, he still gets one final laugh by getting you to take out an integral part of the assassination business regardless.)

Either way, you would still get to an epic final battle, yet one which makes far more sense.

I am not sure if Titan's vampires are outright burned by the sunlight, but they clearly hate it regardless. So, when the Prince left Alfred unable to sire heirs, was it in a night battle? Or was he somehow not a vampire yet?

Perrereich is very clearly much stronger than Arielburg when you first visit it, and I do not really buy that the count was suddenly so transformed by meeting you, he was able to improve everything so quickly in a few years. How, then, does the ending where Arielburg's army shows up to the city the night Prince dies and his mansion burns not lead to Perrereich waging war right after? That alone would have been enough even without the whole "making most wanted assassin our new leader" thing.
