A tradition based on a great tragedy that only seems to breed more tragedy? Awkward Spaceship has a point -- maybe Hyrule needs to revisit its princess naming policy before everything explodes.
There are plenty of perfectly good princess names out there that won't cause powerful evil to arise and threaten the land. Princess Bubblegum doesn't run into too many... OK, bad example. Princess Peach? Oh yeah, kidnapping. Princess Leia? D'oh.
Maybe we just need to get rid of princesses altogether.
