As Sirius had demonstrated, creating a portkey had a strict process. One couldn’t just cast Portus and expect it to be done and over with. First, one had to carve the rune representing safe travels onto the surface of the chosen object to be turned into a portkey. Next, the destination must be set by infusing one’s magic into the chosen object while chanting the address of the said destination. This step coincided with an optional one which was setting an activation schedule or password. Lastly, when the magic within the chosen object finally settled, this was the time to utter the incantation. The whole process was technically quite simple but the second step would be troublesome for everyone since the portkey would lead to an exceptionally distant setting. If Ashley had opted to do this on her own, her core would be dangerously drained and she would earn a long stay at the hospital wing, if not at St. Mungo’s.
