Lieren Lieren is the tomboyish adopted human daughter of Kardan and twin sister of Loania . Together with her twin sister , they faced the horrors of Darkshire and Karazhan to put their parents ' souls to rest . Biography . Kardan raised Lieren like any loving father would in Aerie Peak , teaching her the ways of the Gryphon rider , and she became the only known human to have earned her own stormhammer . However , Lieren still felt like an outsider among the Wildhammer dwarves despite the insistance to the contrary of her dwarven friends , which lead to an obsession with uncovering her past . One night , Lieren secretly followed Kardan to the High Elf retreat Quel ' Danil Lodge , where she made a shocking discovery of having a twin sister named Loania . Loania was raised by a high elf named Voldana . With the truth out in the open , it is with a heavy heart that their adopted parents revealed how they both accompanied their father , a human paladin named Dougan , an old friend they fought beside in the Second War , on his mission to rescue villagers from the cursed tower of Karazhan . Unfortunately , brave hearts and noble intentions were not enough to defeat the evil from with in and they were forced to retreat . Dougan was killed in the process and was left behind . Feeling guilty that they hadn ' t gone back for their friend , Kardan and Voldana returned to Grand Hamlet and delivered the sad news to Dougan ’ s wife Adena . Yet so immense was her grief that her mind snapped and she became unfit to raise her twin baby girls . After some time spent with Adena , it became clear that she might not ever recover . And so , after arranging for Adena to be cared for by a healer , Voldanna and Kardan decided to honor their friend by raising the twin girls as their own . While Lieren and Loania shared little in common aside from their appearance , they both insisted on seeing their mother . However upon arrival of their old home , now called Darkshire , the twins learned from Commander Althea Ebonlocke that their mother was dead . After the loss of the good paladin and neighbor , Adena had committed suicide not long after Kardan and Voldana had adopted the twins , and was then buried in Raven Hill Cemetery . On the way to the cemetery with a Night Watch Militia escort , it was discovered that Adena had been reborn as one of the undead , and was headed with other undead to attack Darkshire . The girls set off on the grisly task of freeing their mother from the rotten prison of flesh by decapitating her . It was then that with their mother ’ s soul finally laid to rest that Lieren and Loania swore an oath on her grave to go to Karazhan to free their father ’ s soul as they did their mother ’ s . A few years later , and the teenagers are now young women . Lieren has become an even more proficient warrior , taking on two of her friends at once in a sparing match , and even holding back . Loania , having been trained as a mage , used a spell to contact their father to see if he still lives . Dougan ’ s spirit warns them to stay away yet Lieren is determined to free her father . Without Kardan and Voldana ' s knowledge , Loania teleports herself and Lieren from Lieren ' s room in Aerie Peek to Karazhan in search of their father . As the twins make their way through Karazhan , Loania , being a mage , starts seeing visions . The first was a vision of Medivh opening the dark portal to unleash the Horde into Azeroth . The second vision is of their father fighting the undead in the tower . Loania uses her vision to trace her father ’ s foot steps which leads her to Terestian Illhoof , their father ’ s murderer . The twins defeat him in battle but Loania is left injured . Lieren wants to get Loania to safety first before she rescues her father . They meet with the spirit of Nielas Aran who ensorcells Lieren in an attempt to kill her and trap her spirit in Karazhan forever . Loania uses a spell to call out to their father once more and Dougan ’ s spirit arrives just in time to save Lieren ’ s life , intimidating Aran into submission . Dougan tells Lieren that it is impossible for his spirit to leave Karazhan and that he has made peace with that . As danger approaches , Lieren and Loania need to teleport out of Karazhan , but Loania is so weak that Lieren offers her access to her lifeforce to beat the the tower ' s pull . Dougan ’ s spirit holds off the horrors of Karazhan while Lieren teleports themselves out of danger and make their escape . As Lieren could only use her lifeforce to power the spell rather than magic , the strain of the teleportation caused her hair to become streaked with white , which she uses as a reminder that she can ’ t win every battle . Although they failed to free their father ’ s spirit , the twins take comfort in knowing that his spirit remains unbroken , just like theirs .
