You must also have at least 1 weapon in the party when going to the ORC camp.
Is this something that orc players have come up with in play? I don’t remember anything on the wiki indicating this.
I’d interpreted “don’t go alone into the Imperial Orc camp” as being because it will make you look to orcs like Citizen No-Mates, given how strong social ties are among orcs, and thus make you look a bit weird and suspicious. Not because of danger; Imperial Orcs are imperial citizens like members of all other nations, after all.
Urizen do not touch at all, although this in itself provides some good RP for both parties.
a) have you seen how many young children there are in the Urizen camp? It’s pretty difficult to make children without some touch going on between the parents. (There are jokes about this in song. I think there’s a commemorative sheet somewhere.)
b) Urizen physical contact is kinda treated as important / private significant in the way the next level up might be. So someone’s boundaries for who they shake hands with might be more like someone else’s boundaries for who they’d hug.
c) That said, some of the Urizen might be messing with you and taking amusement from the confusion of other nations at extending their hand and getting a bow in response. Damn those snooty mountain elves.*
