Actually... i sort of want that everyone can be a minor DM of the Terra...
...to make the Terra a place where you're free to summon reasonable things giving the crew a surprise or a mob to fight at night, do town NPCs in a way currency is actually something to be kept note of or just it entertains both characters and us, make arcs for the crew to progress and seek for the better ending of it and give some thrill...
I want that the only things that restrict us are the terrain, risk of being implausible, creativity block and basic senses.
Maybe i am too idealistic and sentimental.
It's just my thoughts...
