Family Ties in Tibia 

• Fardos and Uman are thought to be the creators of Tibiasula. Fardos later united with fire to sire Fafnar and Suon, who are therefore brother and sister, and also united with air to sire their half-brother Nornur. Uman, on the other hand, united with earth to sire brothers Crunor and Toth and with water to sire their half-sister Bastesh. Zathroth created Brog together with Fafnar and later united with earth to sire Urgith. Brog fathered Garsharak, who then breathed life into The First Dragon (NPC). He became father to Tazhadur, Kalyassa, Gelidrazah, and Zorvorax, who in turn became the ancestors of all Dragons, Dragon Lords (including A Dragon Mother, An Old Dragonlord and Tamoril), Frost Dragons and Undead Dragons (including Awareness of the Emperor and Pythius the Rotten) respectively. Kirok was created when Uman attempted to separate himself from Zathroth together with Fardos and can be seen as their son. 
• Banor and Kirana were married (as the first human couple). Through their daughter Elane, they eventually became the ancestors of Thais, and therefore of all Thaian kings (Tibianus I → Yorik I → Yorik II → Tibianus II → Xenom → Tibianus III). In addition, all queens of Carlin (Elorana → Eloise) are descendants of Banor, for Elorana was Tibianus II's daughter and Xenom's sister.
• Pharaoh Horestis eventually became an ancestor of Arkhothep, by way of Uthemath → Harrah I → Esuph I → Esuph II → Karkhaneses I → Karkhaneses II → Harrah II → Esuph III → Rahmen Tah → Esuph IV → Ashmunrah, who then became the father of Arkhothep. Also, Uthemath had a daughter named Tahmehe.
