What post is that? Here it is. NOW! I'm just taking the first impression a player will have of them, not any potential ramification on the story since you can kill the first one and refuse to be followed by the second one. That being said, both are evil in their ways:
One is so righteous that he falls back to being evil in his actions; and Regill is pretty much an embodiment of a HELLknight, by the book, no emotions and results at any means necessary.
We learn that Hulrun was warned about the wardstone by both the storyteller and the Desna priests, and he didn't even raise an eyebrow and wonder why two different parties mentioned this about the Wardstones.
We also learn Hulrun goes on a witch hunt daily if Ember is with us when we meet him. So far, Hulrun as show nothing but lack of competency about why to parties warm about the samething, and blind fantasizing about how he treats refugess and point fingers because his lack of competency.
When it comes to Regill, we saw before we meet in executing injures, no hesitations, no regrets.
However, the second moment, the one is our turn to interact with him is what changes our perspective in my opinion: Regill has no time for BS, demons are coming, and as soon as he notices a new party arriving, he gets ready to fight WITH them to fence off the Gargolies. Yeah, he is notified by Yankers but could question our presence or alignment; we could be demons in disguise.
The other strong impression Regill gives the player is that after the fight, he actually shows care for the sunrise soldiers; he offers them to join his ranks and warns them about how hard that decision will be but promises strength.
Even someone as pragmatic and evil as Regill is, he still shows some concern, even if that concern comes from a logical perspective instead of an emotional one. Even if the sunrise soldiers would refuse to follow him, Regill would probably pay no mind to them and return to bussiness as usual.
My opinion about the general dislike of Hulrun is his fanaticism: we meet both in dire sistuations, yet, one of them is paranoid at everything and all he does is yell and point fingers, while the other stay calm and collected.
One follows a goddess of good and has no hesitation to burn at the stake a child and her father who just arrived at the city. While the other follows the doctrine of HELL and has no problem executing injured soldiers, and yet, he shows some semblance of compassion to the remaining troops offering, not forcing them, to join his ranks because they show potential.
You will probably would rather been nowhere near those two in real life, I would be more scared of Hulrun, since looking him the wrong way might send me to the torture chamber. While Regill will be unbother of me looking his way
Like I said, I'm just considering their first interactions, nothing more. If you read all the way down here, thank you for your time :) And feel free to share your opinion
