My groups usually think of them as a powerful fey creature who sometimes just whisks people away for an indeterminate amount of time, only to bring them back later.
You’ll need an extra feat to add the time delayed parameter selection metamagic.
Or you could just imbue a nino-magatama with it and give it to a fellow wizard to use it on you.
Way back in high school, we had a massive Mage campaign. Someone brought their asshole boyfriend who was a dick from the beginning by insisting that no, he wouldn’t play a mage. This was World of Darkness and he was going to be a vampire. And he kept being a dick for a few more sessions. Then they broke up, so the DM had his character sucked into an air vent and mushed into a pulp by the razor sharp extraction fans while we were walking down a corridor. And we all moved on like it never happened.
