you can't skip it but you can escape.Is it possible to avoid the orc village trial? I don't see any option to refuse and if I leave the village it I can't get past the tower.
to escape you need to give the orc in your tent a bj then he tells to take your equipment from the chest,take it,
then go out talk to the orc near the village entrance not the dungeon one it, take the one in right(I made this mistake a lot of times)
then you need to take out some bandits with sneak or ask the orc to do it, careful if you ask the orc he will take all the drops. so keep going then you come to the tower which is in the left . now take right the place where you where caught, now you will tell him u need privacy so go to the staircase you will see a skeleton get a escape crystal(show boobs or give 500), and then use it ,
it will take you to the doctor. viola you escaped i dont think you can skip this area since its a main story quest.
