The Fiends and Intrigues of House Karvane

Castle Karvirax, northeastern Cheliax. A sizeable fortification looming over a smallish town bearing its name. This is the seat of House Karvane, a significant player in the Inner Sea trade through the powerful Karvane Company, with several branches and bases of operations throughout the region. Despite this, however, much of the information on the House is kept obscured or is simply unavailable; and outside actors who have tried to look too deep into the House have been found dead or simply gone missing, several times in the past. Dark rumors circle of the house's patriarch, Garavon - of fiendish taint and darker plots within his house - but due to the house's influence, this has previously all been seen as insidious speculation and kept on the down low.

Of course, you would not be here if not for the fact that this is no longer the case. There's now open talk in certain circles of Garavon's machinations against his own kin and descendants, accusations of him being a Tiefling, and stranger things still. What more, the source of these rumors seem to come from inside his own House, hinting that the Karvanes may be on the verge of breaking out into great internal conflict - a prospect that would certainly upset the delicate balance of both Chelish internal power and the Inner Sea trade. Much like any prospective conflict, this means there's both profit and influence to be gained, if one is enterprising and just a bit lucky - and YOU have just been given an opportunity to enter this conflict with a rare ace up your sleeve.

Via a coded missive, you have been called to the edge of the small Nirmathi town of Michsbridge. The sender is one of Garavon's many sons - Elvargian Karvane, thought to have died in battle against Molthuni forces over a decade ago. He faked his death to escape his father's influence, and has lived a quiet life in the north - until now. He has offered you a considerable reward for what seems like a rather trivial task - delivering a certain parcel to his brother Abaric, who runs the Karvane Company's Andoren branch out of the great port city of Augustana.

It's obvious that there's more to it than that, of course, but if you wish to know more you're going to have to start digging yourselves - and who knows what darkness you may find among the fiends and intrigues of House Karvane.

Ding-dong, secret message just for you
"I totally just want you to deliver a secret package to my brother, honest, no trickery, also I was merely pretending to be dead" t. Elvargian
