Sigil, City of Doors...
This is the wiki, to see all the pages you can access, click on “see all pages.” Not too hard. Sigil is a place where knowledge is power, and power is everything. Good luck!
Writing an adventure log synopsis of what happened from your character’s point of view will yield xp and a greater likelihood of taking center stage as I learn more about your character and can include him or her in the story more effectively.
Keeping your character up to date also helps with that, and increases the chance I don’t overestimate your abilities and accidentally kill you.
Here is where you can also write player secrets, something only I will see, so if you want to do something without the party knowing until you want them to, here is the place. I encourage this. Fair or Foul, it turns out some interesting gameplay.
