Pontifex [1-7]
Council of 7
Tremere
Ranks available to starting PCs are detailed in the house rules, section 5.0.3.1.1.1 Tremere. You can find the house rules here.
http://simianpublishing.com/DarkReign_HouseRules_Beta.docThere will be a tremere clan meeting at the beginning of game with the acting regent of Seattle that will undoubtedly answer most of your questions.
With the city basically rebuilding itself, the local tremere will be answering to the Regent of Spokane until the Lord of the West selects an IC regent from the city and a chantry is established. The expectations and restrictions from the pyramid will be discussed at the meeting.
If you have a question about how things work, feel free to contact me directly. I’ve played every level of the pyramid except for tremere.
