Gervisse is a male elven mage who is accused of being the bogeyman by the twins Laerta and Louise. They claim that he looks into their window at night and this sets up the short side quest Laerta and Louise. Gervisse will try to convince the party that a shape-shifting druid named Voltine is the real villain.
“ | My name is Gervisse and, as you can tell, I am a mage. The two young girls within that fateful room face a dark and uncertain future. They have already come under the eye of a powerful druid who goes by the name of Voltine. She has polymorphed herself, into what I know not, in an effort to infiltrate the house and abduct the twins in the night. Please believe me. Voltine must be found or the twins are in grave danger, indeed. | ” |
This results in an entry in your Journal under the quest titled Laerta and Louise:
“ | Old Gervisse, who claims to be watching over a pair of young twins in Baldur's Gate, has asked me to seek out and kill a druid named Voltine. According to Gervisse, she is apparently polymorphing herself in an attempt to slip past his nightly defenses and abduct the twins. There is still something that disturbs me about all of this, but I'm not sure what... | ” |
Speaking with Voltine provides the party a chance to decide who's telling the truth and who's lying and of course it's Gervisse who is the bogeyman and must be eliminated.
