Tainsfield
Tainsfield is a bustling town of around 10,000. The River Tain runs through the middle, splitting the town into Southside & Northside, with three bridges across. The river is approximately 50 feet wide, and dredged regularly. The Southside law is run by the d'Tama, the Northside by the Medici. This town can dangerous, for instance a man was shot dead in the streets, and people just stepped over the body. Armed (short sword / club) bands of 5-8 men in black armour patrol regularly, and watch from roof tops. There is no official curfew, but activities after dark should be performed rapidly and discreetly. There is a large group of urchins and guttersnipes that form an informal network which now serves d'Tama.
The Tuneful Tabor is a high quality Inn which doubles as the local Troubadour Guild HQ. Out of town Troubadours are welcome. General performance quality is good, but avoid the amateur nights. Also avoid the Inns recommended by guards. They will be of good quality, but are closely watched / patronised by the ruling families.
There is an extensive tunnel network through the town, based on the old sewer system. There are popups throughout town, as well as the more usual entrances. However, the d'Tama's have sealed off their entrance through the old well.
Seagate Guild members have an advantage with dealing with the d'Tama's, as Phaeton (known there as Phil) is a scion of the house. In the future he will become heir, as Paul d'Tama inherits from Donald, their father. Donald is not a mage. His wife is an untrained Mind Mage. Paul (probably the head of the household as you read this) is a medium-high Illusionist. His partner, Katerina, is an Assassin, and expert in Rapier and Unarmed. There were no noticeable magical protections around the household when we visited, but this may change with an Illusionist running the business. D'Tama's keep their word in business dealings. They are the local (Southside) law, and leave bodies in the river. Secret contact with Phaeton or Katerina can be made by using a picture of a Frog to indicate your Guild affiliation. The urchin "irregulars" may be integrated into the d'Tama operations in the medium term.
