Magic is computers

• There are runes that can create golems, or perform math like no human ever could
• A rune can only be read or written by mages of the correct school
• Computers are haunted by insect-like ghosts who can’t be seen by the naked eye
• Ward spells, created by mages only for mages, can be used to detect the ghosts or defend against them
• Magic manifests when mana flows through the spellcasting implement
• Old runes are incomprehensible to younger mages, but years of reverse-engineering study from the dedicated ones can reveal their secrets
• Souls may lose their storage device physical form, but as long as they exist, they can be brought back to life
