Yes, soulworkers are strongest when their emotions are at their peak. I do remember it mentioned a few times in the story. Baically Maverick's PTSD is what is holding him back.
Although what I meant is that Veneris might be similar in his ow nway. Although I do agree it seems unlikely.
Anyway his character design seems suspicious to me though. Just saying this randomly since i have no basis to it but what if he is a Soulworker of Truth but he's not seek truth and that's why he's a non-combatant. lol Just throwing it out there.
Other than that i haven't found much of anything recently.
