The Dark Brotherhood eventually caught wind of his actions, and extended an invitation to join their ranks. He was growing weary of living alone, and yearned for a place to call home among people who wouldn't hate him for who he was. So he joined them. Life was good for a while, he was already proficient in archery and stealth, and so he fit right in, he had a home, a family, and he still got the chance to eliminate those he saw unfit to live.
As time went on, he started to worry about dying. He was already old, and his missions were always risky. So he began research in to magic looking for ways to prolong his life. Eventually he decided the easiest way was to just ask Vicente to make him a Vampire, he weighed that living immortal was a good enough pro to out weight the cons of being a vampire. He soon realized that he enjoyed the hunt, searching for prey and hunting them down, And he had found his way to stay alive indefinitely. All he had to do was avoid the end of a blade, which was of no worry to him, being a Vampire, and an expert at stealth.
Eventually the war hit even the sanctuary, and he was forced to leave his home after it was destroyed. He decided to change his identity, and flee to Skyrim with Vicente. The remaining members of the DB left and went their separate ways as well, as not to be hunted down together. On his way to the border of Skyrim, he came across the portal to the Shivering Isles. He remained there for a while, helping Sheogorath as he saw fit, eventually it came down to the event of releasing Jyggalag, and Vicente decided to remain in the Shivering Isles as the new Sheogorath, he had already been alive for hundreds of years, he was already going mad from that, and so he decided what better a place to be mad than this? With that, Inteo left the Shivering Isles, and spent the next few years traveling all of Tameriel occasionally hearing from Vicente and returning to the Shivering Isles from time to time.
He eventually realized that even though death may never come for him naturally, he may still die one day. It was merely a matter of time till some bandit, or guard got in that "Lucky arrow" and finished Inteo off. Recalling Umaril's own pact with a Daedra, he realized he could do the same, as old Vicente was now Sheogorath, and a Daedric prince. He returned to the Shivering Isles and asked his old friend if this could be done. Sheo said "Why anything can be done! I could gut you right here and now! Or I could turn this flower into a snowflake! Ha haha! After an agreement, in which Sheo used all of Inteo's own strength as payment, they made the pact, truly making Inteo immortal. For when ever he is killed in Tameriel, he returns to the Shivering Isles to be resurrected as a Daedra would.
And with that, my Character (Around the beginning of Skyrim) Crosses the border into Skyrim, only to be captured by some imperials suspecting him of being a Thalmor spy. Hence why they were able to catch him, he was powerless, and hence why he did not fight his execution, for he would have just been resurrected in the Shivering Isles. And that, is the story of my elf Inteo.
