I started playing D&D 5e in 2014, and started GMing it in 2016 after I realised I had read the PHB back-to-front, and wanted to think about D&D far more than could reasonably be done with only one character to play.
Currently running: Rise of Tiamat for a group of 4/5.
Currently planning: My first off-book adventure, to follow RoT, for my soon-to-be level 16 group. Should be fine, right??
