The Telvanni suffered greatly during the Red Year in the early Fourth Era, but survived and attempted to rebuild. Morrowind was then invaded by the Argonians of Black Marsh, and in an act of revenge for centuries of slavery, the Argonians focused on wiping out the weakened House Telvanni. Circa 4E 6, the last remaining stronghold of the House was sacked by the Argonian invasion force and Great House Telvanni fell. It is documented that some survivors attempted to flee aboard The Pride of Tel Vos, a ship which was later found wrecked along the coast of Skyrim, east of Winterhold. By this account, a single heir of the house survived: Brandyl Tenvanni, son of Lymdrenn Tenvanni, who was found as an infant by Argonians. He grew up in Black Marsh under the name Brand-Shei.[4] Brelyna Maryon is also a descendant of House Telvanni, so it is possible that the House survived in some form, if not the main family.
