One of the companions Avellone wrote in Pillars, is a dirty old man, who is perverted, racist and misogynistic. 

The only way to complete his quest and discover his story, is to repeatedly camp with him in the party. Over and over til it triggers. You have to get two triggers. Then take him along to a specific main quest. Otherwise you can't complete it. 

The end of his quest, and that bit of story, is interesting enough. But it's far more about his god, than the character himself.

So to recap. Awful deliberately shitty character. Who you -have- to keep around for 90% of the game to complete his quest, and the only interesting thing about him is more about his god, so could have been achieved with literally any other type of character who follows that god. 

Oh and the cut content Avellone bitched so much about? He wanted that character to have raped the other companion he wrote, in the past. 

I'm not even kidding, that's Durance. A companion he wrote, that people laud. WHY.
