i did not know about lycans before i came on this forum
i searched on the internet and find out that Lycan is the name of a fictional race in the movie "Underworld" (i did not see the movie ) but as you describe it is a werewolf

i will try to find the movie and see it one of these days so i can se what are you talking about
i personally did have only minor conflicts with werecreatures untill now
besides these movies is there any old legends about werewolves and vampires being rivals ?
