Reine knew that prior to 6000 years ago, the Akhean Isles were vaguely 'ruled' by the Titans of Mt. Mitikas. Seen as something more than a saint but - generally - less than a God by the Akheans, the Titans were venerated in art and poetry and prayed to as intermediaries or, less commonly, as actual gods. The four eldest Titans - three brothers and one female - gave rise to the four other Titans and a handful of Half-Human hybrid children, the most famous of which were Adrestia, Alkides, Eurymedon, Pthesmos, and Bia, the woman who would be their undoing.
In any event, ignoring for now the circumstances of her tantrum, Bia ended up single-handedly (although some claim Devils helped her out) killing the eight Titans. Nearly all of the Titans, as well as Alkides died on - or in - Mt. Mitikas. Only Eriounios, the Messenger, died away from Mitikas.
Aegaeus, the Titan of the Seas, and one third of the eldest Titan brothers, had his corpse hurled off of Bia. Or maybe he wasn't dead before he hit the ground. Sourced differ. In any case, Bia definitely tossed his body - live or otherwise - off the part of the mountain she was on when she killed him. It was found and enshrined within a great temple in the titular city of the island of Inachus.
Aidoneus, the Titan of the Dead, Cleric of Nerull, and brother of Aegeus and Astraopios, was slain in his Upperdark abode of Erebus, in his own palace. Erebus was said to be reachable via Kharonium, a cave system running through Mt. Mitikas.
Alkides, favored son of Astraopios, legendary hero and adventurer, and supposedly the strongest mortal of all time, was killed outside of the Pantheion, the grand temple and palace that stood at the very highest point of Othrys, the Titan's mountaintop home.
Astraopios, the Titan of Thunder and king of the Titans was slain within the Pantheion.
Euboea, Queen of the Titans and bride of Astraopios was slain within the Upper Gardens of Othrys.
Khalkeos, Titan of the Forge, was killed within his his Foundry in Othrys.
Itonia, Titan of War, was killed within the main temple of the city of Dodona, located on - albeit not at the peak - Mt. Mitikas herself. As the city fell during Bia's rampage, her corpse presumably is still there.
Terpsimbrotos, Titan of the Sun, was slain within the Agora of Othrys.
Hopefully no one got to them first.
