The Drow houseolds of the Tarantulas are made up from descendants of the 13 clans that chose to hold onto Lothiriels memory. Each household will, though may not be able to, trace their lineage to one of these clans.
Over the many centuries since they first split into the Underdark, some clans have become all but extinct, but their memory lives on.
