Yes, sorry, fair point. I didn't so much mean "reduce" as "change". I was thinking in a "mundane" (for want of a better word) environment that magic is harder/takes longer etc (perhaps is more ceremonial) and the dominion is a total nuisance; really it is where the companion characters shine and the magus goes there because of necessity. In the regio's and magical realms magic would be MUCH easier and more powerful (auras of 5+ on a regular basis) and what occurs in the magical realm impacts the "mundane" (So the Crusading Magus helps the crusader by torching a particular hut guarded by a basilisk in the magical realm rather than fireballing soldiers on the battlefield for example). From the Mundanes perspective Magi are the stranger with the pointy hats appearing from round the corner, imparting some strange riddle or useful advice before disappearing round the next corner.
Yes... from the mundanes perspective. From the perspective of the Magus though they absolutely are, and sometimes the results of the labwork might leak out into the mundane world. Perhaps Dragons don't lay waste to a town on the mundane level, they attack on a magical level, superimposed over the town, which would impact the mundane form of the town by fires breaking out, plague, riots and mundane violence what-have-you.
I do miss 4th Ed Hermetic Architecture, I much preferred it... I suppose though it depends on how regios work... regio's can be pretty huge theoretically or pretty tiny. I really like the regio network concept in Between Sand & Sea, some regio's connect with other regio's but sometimes you need to return to the mundane world to get to the next access point (boundary, vestige, microcosm or what-have-you).
So exploring and finding the vast number of routes & regios in an area might take a player party years; as was pointed out elsewhere:
Totally agree, but I would like more of the Tales type books...
Oh I absolutely agree! If only they would redo the 3e Tribunals books to 5e standard!
12 months rather than 4 seasons would be kinda cool from the horoscope/enigmatic wisdom point of view (I'm sorry, but it will be inauspicious/un-apt to finish investing your talisman for the next 7 months... what other projects have you got on at the moment?)
