I don't know much about Torchbearer other than what I learned fromsome Youtube unboxing and review videos plus several posts that I have read in this thread. The impression I get is that it is focused on staying alive, getting treasure to increase one's status, and the choices character's make. To enforce this in play, you have the Adventure Phase, Camp Phase, and Going to Town/Leaving Town.
Is it focused on dungeon delving and survival or can the mechanics also support a session or two of courtly intrigue and investigations? For example, a party returning to the castle where a character grew up as a servant and find the character, in his absence, was framed for a crime and the party needs to uncover who framed him and prove his innocence.
