You came here in that? You are brave
All Agera work with a base-8 system (though of course, in GMing, for simplicity, I don’t). Accordingly, the Mysian system of measuring is based on 8s. From dolon to dolmelphion, the system is fairly straightforward, but, traditionally, after dolmelphion, it becomes a touch more complicated.
Throughout creation there are locations which serve as nexuses of sorts; conduits between one place and another. Such are the rules of translocation that only areas that border each other can be traversed by physical or magical means.
A PC Conjurer or summoner, basically any mage whose sole purpose in life is summoning creatures to aid in battles and various situations, is cursed with a hex, and needs to find a way to undo the curse...before he goes mad, or his fellow PCs throw him out of the party, or worse.
Everything he/she summons, never goes away. So you'll have to figure out what the heck to do with that dire bear or fire elemental once it's done fighting the orcs for you. Eventually a caravan of bizarre creatures either annoyingly ends up following the summoner around, or they go off to cause mayhem elsewhere. Bad news for the poor spell-caster regardless.
