If fate has dropped you into a parallel world, take this friendly advice: beware of helping the first elf princesses you meet. They may come with an entire crowd of unfortunate relatives, packed with an impressive set of problems—and you’ll have to rescue them too. But if you couldn’t resist the temptation and got tangled up in the mess, stock up on paired ancestral blades, a war tiger, and above all patience—because you’re in for truly dangerous adventures.
