The Story of Vladimir
Vladimir is a hemomancer — a Noxian blood mage who has spent centuries studying and practicing the use of blood as both magical medium and sustaining substance. He is old. Significantly older than he looks, because one of hemomancy's gifts is the extension of life through blood consumed from others. He has been doing this long enough that "Vladimir" may not be the name he was born with but simply the name he uses now, which is a distinction he does not clarify.
He is not a vampire in the folkloric sense — he doesn't operate from any principle of necessity, doesn't fear sunlight or garlic, doesn't have a compulsion he's fighting. He drinks blood because it sustains his power and because he finds the practice interesting. He approaches his own immortality the way a hobbyist approaches a long project: with genuine enthusiasm for the technical challenges and periodic satisfaction at the results. He is one of the most powerful mages in Noxus. He uses this power for his own amusement and occasionally for Noxian objectives when they align.
His relationship to mortality — his own maintained, everyone else's progressing normally — has produced the specific kind of person you get when genuine intelligence is combined with extensive life and the removal of most consequences. He is sophisticated and cultured and utterly self-interested, in ways that are charming right up until they're not. He has watched enough people die to find it aesthetically interesting rather than sad. This is either wisdom or damage, and he would say they're the same thing.
