Lina :The sibling rivalries between Lina the Slayer, and her younger sister Rylai, the Crystal Maiden, were the stuff of legend in the temperate region where they spent their quarrelsome childhoods together. Lina always had the advantage, however, for while Crystal was guileless and naive, Lina's fiery ardor was tempered by cleverness and conniving. The exasperated parents of these incompatible offspring went through half a dozen homesteads, losing one to fire, the next to ice, before they realized life would be simpler if the children were separated. As the oldest, Lina was sent far south to live with a patient aunt in the blazing Desert of Misrule, a climate that proved more than comfortable for the fiery Slayer. Her arrival made quite an impression on the somnolent locals, and more than one would-be suitor scorched his fingers or went away with singed eyebrows, his advances spurned. Lina is proud and confident, and nothing can dampen her flame.
Crystal maiden (Rylai) :Born in a temperate realm, raised with her fiery older sister Lina, Rylai the Crystal Maiden soon found that her innate elemental affinity to ice created trouble for all those around her. Wellsprings and mountain rivers froze in moments if she stopped to rest nearby; ripening crops were bitten by frost, and fruiting orchards turned to mazes of ice and came crashing down, spoiled. When their exasperated parents packed Lina off to the equator, Rylai found herself banished to the cold northern realm of Icewrack, where she was taken in by an Ice Wizard who had carved himself a hermitage at the crown of the Blueheart Glacier. After long study, the wizard pronounced her ready for solitary practice and left her to take his place, descending into the glacier to hibernate for a thousand years. Her mastery of the Frozen Arts has only deepened since that time, and now her skills are unmatched.
