The Overmere Family

After the death of Emperor Optimus Overmere (788-848WA), who had ruled the Empire for 32 years, the Imperial Family of Correhome devolved into a sibling rivalry. To the best of your knowledge at the moment, based on information provided from The Hobgoblin Who Got His Dog’s Throat Cut And His Balls Almost Torn Off and the Overmere Geneaology from Adalberto Veno's library, there were 12 Overmere children but you only know scraps about their relationships. Thalia Overmere in conversation with Clytemnestra "Fanny" Glitters, stated on 17th Winterfall 866WA that "as far as she knows" there are seven left alive. That seems consistent with the book, published in 864WA.
The Overmere siblings appear to be:
(By Martia Overmere)

• Emperor Ericus Overmere (813-848WA) - Deceased and the heir apparent who may briefly have been Emperor without his knowledge, as you learned in the dream about the Petition of Sylvio Overmere;
• Emperor Kern Overmere (820WA-) - Suspected by Sylvio Overmere of Ericus' murder, and possibly Optimus';
• Thalia Overmere (820WA-) - Presently in exile in the Wandering City, having been banished in 850WA;
• Fluvia Overmere (822WA-)
• Numerius Overmere (825-848WA) - Deceased;
• Camilla Overmere (828WA-)

(By Servia Overmere)

• Sylvio Overmere (830WA-) - Well known as a brilliant general of the troops in the Portavian front. Offered a younger sister to Kelemvor in exchange for proof of Kern's fratricide during the Petition of Sylvio Overmere. Tarts McGillicuddy advised that Ulf, the proprietor of FISH STOR in Lakeshore, had information about him;
• Christus Overmere (831WA-) - Archbishop of Maulden, somehow involved in Imperial finances, bridge between Thalia and Kern Overmere;
• Cassius Overmere (834-862WA) - Deceased;

(By Lucy Overmere)

• Decima Overmere (847WA-) - Now confirmed as a member of the Royal Family, it seems plausible that she was the baby in the vision of the Petition of Sylvio Overmere;
• Caius Overmere (849-852WA) - Deceased;
• Felix Overmere (849-852WA) - Deceased.
