Okay, I have the second full game in.
Two of the players were a bit distracted and unorganized in their play, leaving pauses in play. I pulled out Fairie Fire for the first time and it really aided the sole combat. I really like the advantage concept in 5e, it allows for a better consistency in roll results.
As to the mechanic, we have discovered the operating mechanic of the game, forgotten teleportation circles that access other teleportation circles set on linear ley lines like a compass. Now, we need a plot push to direct us to our next mission and over all purpose.
