Eras time ago:
There were Titans Cronus and Rhea, who once ruled the universe, later they had children gods Hades, Zeus and Poseidon and goddesses Demeter, Hera and Hestia. When Hades was born, Cronus swallowed him as he had swallowed his other children at birth. However, Zeus escaped this fate, and he tricked Cronus into taking a potion that made him vomit up Hades and his siblings. Together these gods and goddesses rebelled against the Titans and seized power from them. After gaining control of the universe, Zeus gained control of the sky, Poseidon took the sea, and Hades received the underworld. Hades is the god of the underworld, the Kingdom of the Dead. Hades was the only god not to reside on Mount Olympus, dwelling instead in a dark palace beneath the earth and intended to remain in there forever... Many eras have passed and new kind of beings, human were born, and as these beings are mortal, none of the gods were allowed to intervene into human life. And so the true story became mythology and people gained the rule over the world...
It was a usual nice sunny sunday at Croft Manor and Lara relaxing outside at the garden drinking coctail and enjoying the sunny weather while Winston suddenly run in with a phone giving it to Lara:
???: Lara, it is me Kurtis, I need your help right now!
Lara: Oh, it is you, so what have you done? I cannot help you from every stumble you make!
Kurtis: No time for jokes Lara, there have been very bad reports from Greece near Elis. There were some weird creatures observed. I went on expedition myself and saw it on my own eyes, one of those creatures was hunting me and fortunately I got rid of it but I am wounded and unable to help you.
Kurtis: Yes. I hope I am wrong but I have only one explanation for that.
Lara: Ok, I am all ears.
Kurtis: Elis is a place where there is a Hades temple nearby and I have worries that the creatures found a way from underworld.
Lara: Are you serious?!
Kurtis: Listen Lara. It is said that if an immaculate soul will be once spirited away into the underworld, a portal between underworld and our world will be created.
Lara: Ok then, it is my turn, you relax, I take it over...
Kurtis: Thanks Lara and one more thing, be aware of the Cerberus, the protector of the underworld. Good luck Lara.
Lara: Hm, just between us dear friend, once that creature meets me he will be really surprised!
And so Lara is taken to the wilderness of Greece and is about to go the way through the nature and temples to reach Elis, The Temple of Hades...
