Jupiter

Jupiter, previously known as Tinia, was a member of the First Civilization. Alongside Minerva and Juno, he took charge of the gathering and testing of information within the Grand Temple, in order to circumvent the First Disaster.

He spoke with one First Civilization descendant in 2012, Desmond Miles.

Grand Temple
"Both before the end and after, we sought to save the world."

- Jupiter.

Upon the outbreak of the Human-First Civilization War, Jupiter was one who chose to find a means of preventing the coming disaster.Six seperate means they tried, each one failing, aside from one, which would require the touch of a descendant of their race to activate, which would shield the Earth in a planetwide aurora borialis.

On the construction of Temples to research methods of doing so, Jupiter, Minerva and Juno were given the responsibility of sorting and sampling the information. The three convened in the Grand Temple, where all the findings from the Temples were gathered, in order to select and test them.

Before the First Diasaster struck, Juno was found to try and enslave humanity, to which Jupiter and Minverva imprisioned her within the Grand Temple, as a means to prevent her from escaping.

However, the First Disaster fell upon them, burning the Earth and wiping out nearly all members of the First Civilization.

In 1499, Minerva mentioned Jupiter in her warning to Desmond Miles, who she addressed through the Prophet, Ezio Auditore da Firenze.

"Take my words. Pass them from your head into your hands. That is how you will open the way."

- Jupiter to Desmond.

In the year 2012, Jupiter spoke with Desmond himself – who he referred to as "the Cipher" – in the nexus of time. There, he told him of his work with the Temples and of the First Disaster.

In order to prevent a repeat of the catastrophe, Jupiter urged Desmond to seek out the Grand Temple and told him the means of opening the way.
