Of course there's the Ynwnn fella in the wilderness who buys them as well. At least its only half the trip to Ojaveda.
True, Mordan... but the Ynwnn fella has some rather nasty neighbours who have a habit of wandering over to investigate any visitors. For a new player looking to sell their first inventory load of hides or skins - that's fairly dangerous shopping precinct to venture into. Perhaps if you are a new player, you could try asking in-game for an escort or two to accompany you to this merchant in the wilderness, and to see you safely back to town.
It is longer to travel to Ojaveda from Hydlaa, but it is safer... most of the time anyway.
