Example:
OC 1 enters and warms her hands on the smoldering fire, getting off her horse (Can be any prompt for entrance). she makes coffee and rests.
OC 2 (From another User) limps in, his arms wounded from a wolf attack. He and OC 1 talk and rest together.
As they talk, OC 3 parks its tank and walks into view. The conversation can now move to 3 people, and silence or speaking is optional.
The user behind OC 2 has to leave, so they wish good luck and takes his bags and walks off into the night.
Now OC 1 & 3 are left talking to each other, and they can have an infinite amount of interactions. OC 3 can suddenly jump and maul OC 1 in a fight, OC 1 could suspect OC 3 is malicious and threaten, insult or negotiate with OC 3
In the middle of this, OC 4 can walk in and yada yada you get the point
