Invincible was Arthas' faithful mount until he rode him in a snow storm and tried to jump some mounds he did as a child w/ Invincible and didn't make it. It broke both the legs of Invincible and he had to put him down there... Thus the grave site (that was dug up... read main page). After Arthas took his sword and returned home he rose Invincible from his grave and made him his undead mount, which he (should) still ride today.Originally Posted by VSUReaper
My deal is why do we get to ride him? Its his mount, and from lore Invincible was very faithful to Arthas and i would think he wouldn't want to be taken by anyone. But meh to lore i guess.
