I suggest that you should read the Arcturian Heresy. It explains Tibers backstory and even a bit of his ascend to godhood. I'm no expert on his backstory, but I know almost anything about how he became a god.

I first want to say that Tiber wasn't the first Dragonborn. Miraak was. The first 'official' Dragonborn was Saint Alessia.

Tiber, Zurin Arctus (Tiber's Imperial Battlemage) and Wulfharth (a atmoran Shezzarine) performed something called an "Enatiomorph". A Enatiomorph happens when three persons or Et'Ada mimmick the fight between Anu and Padomay. Each Enatiomorph needs a King, a Rebel and an Observer. The Rebel becomes at the end of the Enatiomorph the King, while the King becomes the Rebel and the Observer is the only one who can say what they are. The exact event is described in the Arcturian Heresy.

They did not only perform this Enatiomorph. The combined Oversoul from them (which is called Talos) mantled Lorkhan. Talos took his place in the Aurbis and stabilized Mundus.

Tiber achieved CHIM before he performed the Enatiomorph and mantled Lorkhan. CHIM is the realization that the Aurbis (the Universe) is a dream of an unconscious entity called the "Godhead". A person who wants to achieve CHIM needs to realize that everything is actually the Godhead and that Individuality is a lie, but they also need to have enough willpower to say "I". What I mean with this, is that a CHIMster needs to realize that everything is him, but that he is still something different. If a person suceeds in both of these requirements, they become a CHIMster and can alter the dream of the Godhead. If a person fails in the last requirement (being able to say 'I') they Zero Sum. Zero Sum is basicly the total deletion from the Godheads dream. A person who Zero Summed will never appear again. Tiber succeeded, and transformed the dense jungle of Cyrodiil into what it is now.

All these three things made Talos the most powerful god in the Aurbis.
