|Lifetime||After the Mending|
Riku has always had two different passions: the study of spellcraft and the study of life. The mage could never choose only one of them, and unfortunately had no time to master both. He managed to find the solution to his dilemma through an ancient illusionist's spell: he secretly split himself into two reflections, and each Riku trained and studied for years in its chosen field. Today Riku is regarded as a master wizard of both disciplines, and few know his secrets. The two reflections never stray far from each other, and when danger threatens, enemies must face the power of both Rikus.
