...you need a day or two to let us know what those might be?
The "adventuring" is a good distinction on the PPM scholar. It implies that a character, or adventuring, has a required Physical component to it. Tomb Raider is a good choice, but is there a medieval equivalent? Also interesting to see rogues and merchants in the same category. Does the handling of large quantities of money constitute a class characteristic? Are merchants less physically oriented than rogues, or is that not a necessary distinction?
Tomb Raider is just a more heroic title for the Grave Robber, a role that did exist in Medieval times - in a Europe=based setting you've got a Tomb Raider digging in to ancient Barrow mounds to steal the crown of a buried king, in the fantasy setting that gets complicated when that King and his guards wake up and try to stop you.
For me the MMP line implies Skills + Physical ability. Thats obvious for Rogue but also works for your merchant if Social Skills are emphasized. For Medieval Merchants I was envisoning the Travelling Tinker who goes from village to village selling his wares while avoiding bandits up to the owner of a Merchant Ship, transporting his cargo to distant ports for sale, negotiating deals and also fighting off pirates
Scholar is Harry Potter-esque sans Magic but it doesnt just have to be old sage consulted for ancient history and obscure facts, Alchemist is the obvious extension as I was wondering where that role might fit.
I also once had a PC decide to play as an Architect/Civil Engineer, as DM I had him employed by the city to oversee construction of defenses on the walls and then excavate a city sewerage system (Paris Sewer was begun in 1370)- Scholar would cover Architect too.
