It's adressed in the scene. But, basically, any force of men that could be asembled large enough to go on an expedition to bloodmeen would be a huge expedition. Requiring lots of provisions and having to go across rough terrain. Is it plausible that Rowan could have grabbed like 10 guys for it? Sure. But, at that point, Rowan was better off going himself and just trying to use being sneaky.
I do believe he can master more than 10 men for that expedition. Yes he is a dirt general and nobles hate him, but he still has some connections from the war plus he is resourceful man, i bet he could make a good plan. Instead he went into obvious trap, knowing that were not ordinary demons. Still it's way better prologue than the previous one.
Also i don't know if it's only me or it was intentional, but the second part of rewritten prologue has no sound at all. And of course i don't know if i should report some inconsistencies to you, but will list some maybe it will help idk.
Rowan wearing the necklace in his sprite while talking with Werden (before even coming to Bloodmeen):
Or while Andras casted his magic on Rowan:
The description said it was red colored, but in CG it was kind of blue toned (small thing i know but still).
Also this :
in some cases the back of his hood is missing.
Oh almost forgot but there was a scene when Rowan came back from the forest ambush during Arthdele invasion with CG of Jezera holding Alexia on the street. Strangely Andras was also standing there, but text suggested that he was trailing Rowan in the forest and came after to save Jezera from knife stab. I think he shouldn't be in the picture then?
