Both campaigns start in the city of Reth-Hi, a city with a mixed population and under the local jurisdiction of the Ancestral Keepers who watch care for the Lost occupying the Old Capital Hill. The city is roughly nine miles square, and straddles the juncture of the Silverbed and Bridux rivers, which flow from the west and southwest respectively and join in the center of the city, forming the Silver Bridux that continues to flow to the northeast.
The southwest of the city, between the two rivers, is the poorer side of town, with heavy criminal activity and a large Rat population. This area is mainly lawless, as the Ancestral Keepers have neither the care nor the people to police it.
The City Proper around the juncture of the rivers contains the bulk of the population, especially the Ferrets and Foxes, with the Viper's carnivals and the bazaar and artisan's districts being a bit further down-river. South of the bazaar, at the edge of the carnivals are the Arenas, run largely by the local Python population.
The Bears in town mostly live in suburbs north of the Silverbed, outside the City Proper, where it's less crowded. Their side of town hosts a semi-permanent enclave of the Sandtusk Druids, where many Coyotes have set up a small subdivision to the city.
East of there, north of the City Proper and near the Old Capital Hill, are the Raven's libraries and the public offices which attract most of the Cranes. The Tiger's local monastery is also in this area.
A few miles outside the city to the north, the Frostwhisker Boar tribe has settled for the time being.
Recently, there have been reports of Wolf sightings along the Bridux, not 20 miles outside the city's limits. It is even whispered that they've been spotted in the 'Undercity,' the sprawling network of tunnels and labyrinth style sewers that help drain the delta between the two rivers and that the crime rings use as a base of operations. It's rumored to be as large as the actual city itself, though few even among the Rats know it's full extent any more.
The 'Light' Campaign starts in the evening at the 'Bear's Cave Inn.' You have come there to meet Jonthral, a Coyote Druid from the Sandtusks who has been working closely with the Ancestral Keepers. He is hiring help for 'clean up work' on the Old Capital Hill. The rest of his flyer is even more vague, and you easily surmise that there is risk involved.
The 'Dark' Campaign starts in an unnamed tavern in the Undercity, where you have been contacted by the Rat, Rotgut, looking for 'skilled workers to help accommodate new acquaintances to the city and do odd jobs for them as required.' The rest of his flyer is even more vague, and you easily surmise that asking questions is likely not welcome.
This information should help you decide, and is crossposted to the summary thread in the houserule section.
