House Do'Urden was a well respected house, in high favor of Lolth, until Drizzt saved the life of Ellifain, a young surface elf. At this point, the credibility of House Do'Urden crumbled and during the coming years, they grow weaker and weaker.
Drizzt leaves his House, and escapes into the Underdark, while matron Malice fails her Zin-carla. House Baenre attacks House Do'Urden, killing all (except for Malice, Vierna and Dinnin. Briza kills Malice, and the siblings join Bregan D'aerthe to survive). This is essentially the end of House Do'Urden.
