Majyyk

Elves are in control of the mysterious force known as Majyyk. It's most likely similarly pronounced as it's more well known counterpart, magic, and they operate on the same level. The Prisoner doesn't question the notion of Majyyk and has a terrible stat for it anyway so it's fairly moot.

The Elf Mage is a practitioner of the fabled Majyyk as well, and uses it to assault foes with various wondrous feats. One of these is being able to create Windows at will.
