Over the past few days I've seen folks with two companions. I'm used to donkeys or some such following folks around, but my understanding is that you can have a companion, or a donkey, but not both. But this is a "human looking" npc.
Did I miss something? This second NPC following the player was called Mercenary. The player would not or could not answer my question.
What's the deal?
Asking for a friend.
