The dread sword known as the Trol'kalar (troll slayer, in the ancient tongue), was first known to be wielded by Strom's most capable warlord, Lord , during the Troll Wars. After the war and with the departure of Thoradin's ruling descendants the Trollbane family ascended to the throne. The Trol'kalar image changed by also becoming a true emblem of power in that region, being rightly wielded only by the direct descendants of Lord Ignaeus as a symbol of rulership over the glorious Kingdom of Stromgarde.
The Trol'kalar's fame (or infamy) is probably attributed to its ability to easily dispatch any troll with a few slashes. From there came its name, Trol'kalar, and very possibly Ignaeus' own nickname which later became the new name of his bloodline, the Trollbane family.
After the Third War
With the mysterious death of Stromgarde's last ruler, Lord , and because of the fragile condition of the Stromgarde nation, the Trol'kalar was sealed with Thoras in his tomb awaiting for the day when a new champion would rise from the people of Arathi Highlands and bring honor and glory to maybe the greatest Kingdom Azeroth ever knew.
A symbol of power or a tool of destruction? Why not both? The very name Trol'kalar is capable of making the mightiest troll tremble. So amazing this sword is that the very trolls, quite aware of the power of the dread blade, to brave members of the Horde, so it can be used against the trolls of Zul'Gurub. For they alone wouldn't dare to risk facing the Trol'kalar ever again.

This bastard sword is notched and old, but its appearance belies its sharpness and balance. Trol'Kalar pulses with a dim white radiance, almost as if alive. The weapon’s name means “Troll Slayer” in an ancient tongue. The scion of the Trollbane family, Prince Galen of Stromgarde, wields Trol’Kalar against forsaken, the Syndicate, murlocs and ogres instead of its traditional foes. The blade still proves deadly.
When the Trollbane family manor was hit with a surprise bandit raid while much of the house guard was out fighting the Horde, a human servant called hid the family's artifacts in the kitchen, filling the priceless chalice of opal voices with gravy, tossing the ancient sword Trol'kalar into the pile of pig offal and putting the cloak of elemental protection on himself and jumping into the massive kitchen fire to hide. Prince Liam, grandfather of , was so impressed with his servant's ingenuity in hiding the castle's artifacts that he appointed him Caretaker of Artifacts with a staff of two, and commanded the young servant to come up with a better plan to protect the artifacts.
When a troll is slashed by this bastard sword, it cannot regenerate as it would when hurt by a common melee weapon. The wounds heal at their normal rate, just as if the troll victim didn't count with additional regeneration powers at all. The Trol'kalar also procs additional holy damage to all evil creatures (trolls included).
The Trol'kalar curses any evil creature attempting to use it with one negative level (debuff). This curse inflicts the wielder as long as the sword is wielded. This one negative level curse cannot be cured nor dispelled, it will affect the wielder as long as he has the sword at hands.
