I've got a player delving deeper into the mysteries of the ancient mercurians, and I'm trying to work out what mystery virtues or breakthroughs might be found through such investigation.
What would you guys suggest, other than those suggested for the neo-mercurians?
Note: As the details on the Mercurians are quite limited, other than that everything they do seems to be in the form of rituals, I have decided to state that they're capable of granting temporary powers, as well as delayed spells that they can use later, to grant them some capabilities that could have been combat-relevant.
Mercury was a god of transformation, boundries, travel and communication, merchants, thieves, and the guide of souls to the afterlife. Boundries is utilized in the aegeis, transformation is fairly well covered,and travel is implied by at minimum hermes portal, but the guiding of souls is one which is certainly very little touched upon and likely to have been the most repressed by the order trying to work amongst and as Christians.
I'd agree with the psychopomps aspect (Nightwalking anyone?) but when I think of this, I think Expanded Road Magic. Variations of the Illusion parameters eg Duration: While (traveling) or Duration: Journey. Also Target: Company.
I worked some of this out at some stage - I seem to recall a higher level Road Network Target and something about enchanted milestones.
Can't remember if it's an upcoming SubRosa piece, lost in my scratchpad files or even submitted as part of an official supplement and ended up being cut out. To be honest, even if I could confirm the latter, I suspect I couldn't tell you due to NDA.
If I find them I might polish them up and repost them on my blog in the Redcap section. Should probably do that with Journey + Company, IIRC I suggested they were known to the Milvi Antiquiti as a Minor Mystery or similar.
