Lunching on Lamias is for recording the exploits of my characters and those of the other people in the campaign, through the form of adventure logs. Whether or not they're in character depends on what I'm up to and whether or not I'm a player or the GM. Currently it will be covering a Play by Post on reddit that I'm a player in, as that's the only active campaign I'm a member of.
Edit: Lunching on Lamias will also cover any random stuff that's related to gaming that I do/like. See Plot Hooks and Quotes, and/or Building A House, for examples.
