Tiberius

Ancient roman dude from the Greece area.

In life, Tiberius was this lazy-ass noble son who grew up in the lap of luxury. Responsibilities? Never heard of em. He'll just leave everything up for someone else to deal with. It worked out for a while, so why stop? It's not like he's a lowly peasant. His purpose in life was to enjoy it, and that's it. Everything exists to serve him, and basically he's a vain, spoiled brat at heart.

The details of his turning are currently quite muddy, but it did involve someone trying to drown him. Unknown to the the killer though, he was previously bitten by a daywalker vampire at a party earlier in the day. Just a little sip, enough to get some of that vampire venom into his system. So of course, Tiberius didn't actually die. He turned. 

Fast forward a couple centuries, and he's quite possibly the laziest vampire around. The mighty house of his family has long since already crumbled down from greatness, and he's left with... just about nothing to his name. So what does he do? He takes naps, of course. It's very energy-preserving. Often these naps take place in coffins that do not actually belong to him. Besides, this way he doesn't really need to go through the hassle of finding living creatures and people to bite. He's honestly quite tired of it. Where did all his servants go? Ah right, they all died. Shame on them. How dare they be mortal and die out while he's still around. 

Once a graverobber found him in a graveyard, and it pissed him off, so he switched places with the robber.  See how he likes being buried alive. Basically, he shoved the man into the coffin, but not before he had taken a good, long sip. I mean hey, free blood delivered straight to his spot! How could he not?

...Anyway, so he may have been responsible for turning the (future) Lord just then. He's not fully aware of it. He normally just bites for that sweet, delicious blood, and leaves them alone after that. Whether people die and end up turning afterwards is not really his problem.

Lately, Tiberius has been napping for the past thousand years in some undiscovered tomb. He genuinely has no idea what humanity is up to these days, and he really doesn't care much either. He does not even know any modern languages. It's not his world anymore. 

Let him rest.
