Hours a night are spent manipulating the corporeal limbs to stimulate the ghost limbs so they rest during the day and don't cause distractions or make demands.

There is a certain spell required for league admittance that requires a 2 am hotel room offering using twin electric devices. Neophytes often travel notable distances to practice this critical and difficult spell out of range of their masters.

Lamps are not requisite--hair dryers and even electric shavers have been used--but everyone knows the spell is stronger if the items used belong to the hotel room.
