Ellery is an experienced GM and has been playing and GMing tabletop games for many many years. They are very understanding and thorough when you have any questions and concerns during the lead up to, playing, and after done playing, a campaign and session. They are wonderful at helping you to prep for a campaign (including what to expect, help with your character, clarifying rules, etc.) and they helped me despite the fact that I missed the Session 0 and the start of the campaign was only a few days away. Their campaigns (from what I've played so far) seem very tried and tested and tend to have lots of great adjustments from the DnD source materials that WotC provides. Instead of cut-and-paste straight from the book Ellery provides lots of great added mechanics and details to the campaign that are very helpful and they are always upfront about what they change and why. Great DM to have, especially for first time or returning players, as they lay everything out on the table and answer any questions, concerns and quires a player may have about a campaign or the mechanics and rules of DnD in general.
