They can be found just inside the zone line to Vanern Swamp. I found a large concentration of them along the East wall just North of the entrance to the zone.
Be aware that there is a level 55 spider that roams in this area. Small Orms conned blue to 41 and regular Orms conned blue and yellow.
Regular Orms drop an item to be used for a kill task that starts in Galpen.
