I agree. It feels like a massive info-dump. You have two points in there:
(a) character introduction
(b) world building info-dump
Everything in (b) doesn't need to be in a prologue but can be told in the story itself. And for the few lines you do for (a): "Becoming an adventurer for one born completely average was not an easy task, but Rohl was not so easily deterred, which put him in his current predicament." The first sentence of the first chapter already tells me 90% of the important stuff in (a).
Right now, the prologue reads like a bit of waste, though that is just me. It doesn't really builds the main character, it doesn't set the atmosphere of the story (in fact, the narrations feels off to me), and it doesn't introduce one central main theme you are working towards to.
To me, a prologue should be used to either introduce the topic/theme of the novel in a way you can't do in the story itself, or to give information that the readers otherwise will only get way too late. In your case, both aren't really done. Besides a generic "there are dungeons" (which I already get from your tags), there isn't any information worth remembering outside the stuff you tell once more directly afterwards.
So yeah, to me, it isn't needed and should either be written or just deleted.
Though I've also seen enough novels have success with a prologue like this...
