what if there were a cloud technology mystics only building in town, and as long as it remains charged (im thinking 100 ranks worth of mental energy= 1 hour) there is a portal available to activate whatever quick transport people agree to in this forum. Then you can you use the power, reliably with mystic present, and have chance of monster spawning if no mystic present. You go through a small ethereal zone, with cloudiness on either side, and walk to the end. This end should be a public zone in town center, and if people really want to they can make a small lobby of the mystic only building, and have people ushered out.
The mystics should get a small amount of experience for each mental drain, with the option of sacrificing health and balance for increased power. Mystics may do this and leave if they choose, as it should be a safe area to conduct the ritual. With combined energies, there should be a charge on the device to allow fair times without a mystic present, but energy available to use the powers.
I was also hoping there would be some sort of punitive measure for summoning people home.. Like ethereal spheres get 10% more dangerous spawns, and eventually resulting in some kind of town invasion (every nth time using this power, and with plenty of warning)
As for the teleporting power, I think there could be makeshift portal kyeums that last for a long while. If one is there, you touch it, damage it a bit (less damage with mentus) and get sent home to the tc designated spot. This could link the ethereal powers with the cloud technology, and have all kinds of weird debates and fun mysteries to solve regarding how this can be.
Again a good idea mr Daimoth
