  • How much between-session stuff do you enjoy?
    I use legendkeeper.com, which costs a few bucks a month, but if you or someone else at the table is handy with web tech it's very easy to set up a basic wiki for free on someone's web server. Source: over 3 years ago
  • I need to create a "relationship web"
    You should check out [LegendKeeper](http://legendkeeper.com/) (there's a trial) where you can create articles and link between them. You can also do visual linking for relationships, and have maps with pins on them for locations. Source: over 3 years ago
  • Port Moors
    Sweet. I've been accomplishing the same map and pin thing using legendkeeper but I have to pay for that + it's a web app, so definitely going to add leaflet to my obsidian and give that a shot instead. thanks! Source: almost 4 years ago
