Falanu Hlaalu is a dunmer alchemist, part of House Hlaalu, and owner of All Things Alchemical in Skingrad. She will direct the player towards Sinderion when shown a nirnroot sample.
She is a necrophiliac and it is hinted that she fled or was exiled from Morrowind where necrophilia is considered an especially heinous crime by the dunmer who value the remains and spirits of their ancestors highly. House Hlaalu’s influence in Morrowind and close ties to the empire are likely what saved Falanu from a worse fate.
"Not much business here, but I can't go back to Morrowind. It's just like anywhere else in the Empire. By the way... do you happen to know what the fine is here in Cyrodiil for necrophilia? Just asking." -Falanu Hlaalu
"Maybe it's just me, but I find Falanu Hlaalu really odd. And I've seen him hanging around the graveyard with a strange smile on his face." -Towns Folk
