The World of Variance is set in an age of magic and science with magic being predominant. Most places have indoor plumbing complete with working toilets and showers. Guns and high tech items do not work here. It's fine if your character comes from a modern day world and entered Variance through a portal or something, but any items like guns, ipods etc. carried in from that modern world will not function properly here.
On Variance, certain items like magical communication mirrors (similar to modern day cell phones) are created by both mages and scientists. Instead of working on batteries, such items usually need to be recharged by a mage a few times a year.
*imagines being able to take cell phone to some guy who waves a mummified chicken's foot over it, instead of paying stupid sprint bill every month and giggles*
