@Aristocles Regarding the size of the tower, in a lot of my settings Mage towers are somewhat extra dimensional, y’know? Tardis-like in that there are more rooms than there ought to be space for when you look from the outside. It means that the setting itself can be ever-expanding and you can later introduce new areas if/when they become relevant, by simply stating that the tower doesn’t reveal all of its rooms until they become relevant.
Also, anyone who knows me would tell you that I love small characters who take on massive tasks, so I’d definitely like to make a little Halfling/gnome/goblin/whatever other short races we have, who uses his size to his advantage when battling monsters. You can definitely expect at least one mini-student from me.
