Funnily enough in the fan fiction section, my "fifth season" of my Mystical Realms Sagas was
Emperor of the Trolls
Shameless self publicity - but how could I resist given the subject name. 
BTW if you go to that section and wonder where Season one and two are, well season one premiered on a forum that no longer exists and season two was on one of my websites
All seasons involved trolls
Season One
Season 2
From season three onwards (Season three premiered here last autumn) this was one of the main trolls
and is classed as one of the good guys, even though in seasons one and two his farther was the main baddie.
