3 Inches of Blood. They're an amazing Vancouver band. I'd actually concider them my favorite band. If you like metal, or even hardcore, you should listen to them, they're a fusion of tonnes of different things. Alot of their lyrical content is about epic/medieval battles. One of my friends said that they are the Judas Priests of their time (you'll see why when you hear them :D).

Here's a sample of their lyrics:
3 Inches of Blood - Destroy The Orcs

kill the orcs, slay the orcs, destroy the orcs
you returned late home that night
evidence all around you from the fight
you see your familys blood spilled on the ground
theres no trace of the orcs to be found
take the broadsword in your hand
follow the orcs to their camp
you will have vengeance in blood
with their heads they will pay the price
spill blood
on their trail we hunt them tirelessly
spill blood
bloodshed eases their loss
spill their blood
their decapitation leads to the cessation
of the sadness, of the woe
spill the blood
