So good! Man, I want to play this yesterday. Art, vibe, writing, all fantastic. The maps! I could go on.
My biggest thought, and it's more of a concern rather than a criticism; I love the story and the quest to restore the blade. But I worry that it could lead to one player getting Main Character Syndrome™. The right group could definitely share the quests equally, or a good Warden might include other things to let other PCs shine, but just a thought I had.
Otherwise, just so, so great.
