Okay, I'm just going to embarrass myself and come right out with a question I really should have known before taking Voiding and Glyphing. To put a Portal into a Focus do you just push the portal onto say the paper where the focus is drawn? Or do you have to summon the void right on the paper? Can you summon the void through solid objects? Does it take more Djed? What happens when the Void disappears? Would it not leave a portal shaped hole? I think I detracted from my original question.
Essentially I am hoping to make a Scroll that opens up a Portal to the Other Side. Intended use? I want to be able to lay them out on the ground and then maybe cover them with leaves and get people to fall into the Void. Maybe not quite that but I would like to get a grasp of Voiding and Glyphing because it is suddenly not as easy as I had originally thought.
