Be welcome to the Library of the Great House Telvanni, traveller. You have questions?
Where can I find the Telvanni?
You might find them around Heimlyn Keep, unless they are busy in other spheres. Feel free to contact @manavortex, @Sethize, @Valorin or @SpaceMarine88 in-game.
I have no idea about your setting, where can I start?
Feel free to browse the Wiki. You can find it in the top navigation bar.
Who is important? What do the ranks mean?
It is rather simple. Treat everyone how you would want to be treated. You can find an explanation of the ranks and a who is who here.
