Invincible was born to the mare on the Balnir Farmstead in Tirisfal Glades, in the winter of the year Stormwind fell. Prince Arthas, then nine years old, was present when he was born, and was given the horse by the Balnir family, who bred horses used by the royal family. The horse had a white coat, different from the usual Balnir stock, which normally had gray coats. Arthas had considered naming the horse "Snowfall" or "Starlight", but in the informal tradition of Lordaeron knights and nobles naming their steeds after a quality (Uther's was "Steadfast", King Terenas' "Courageous"), he named the colt "Invincible".
Ten years later in winter, before Arthas was inducted into the Knights of the Silver Hand, Arthas' exertion in the numbing cold resulted in a crippling injury to his beloved Invincible. Too far from help and unable to heal the stricken horse, Arthas was forced to kill him in order to relieve his pain. He was buried on the grounds of the Balnir Farmstead at Arthas' request. Invincible's death was one of the events that inspired Arthas to become a paladin.
After the fall of Lordaeron years later, Arthas - now a death knight - ran directly from Lordaeron after murdering his father, to the Balnir Farmstead where Invincible was buried. With the power of Frostmourne, Arthas resurrected the horse as his undead steed. Now fully living up to his name, Invincible could become a spectre and disappear, to be resummoned by Arthas at any time.
During the Scourge's siege on the Sunwell, confronted Arthas in single combat, severing Invincible's forelegs with his runeblade, , to dismount him. Witnessing Invincible's injuries brought on a surge of memories and sent Arthas into a rage, during which he shattered Felo'melorn and struck down Anasterian. This time, however, Arthas was able to necromantically repair the injuries. It is likely that Invincible served as his master's steed, even after Arthas became the new , though has also been referred to as his mount.

Beloved steed of Prince Arthas Menethil
Loyal and great of heart in life, may you find peace in death.
Pure streams and green pastures, devoted friend.
The open grave was introduced in Patch 3.0.2, Echoes of Doom, but went unnoticed until just before the Zombie Infestation phase of the Scourge Invasion, which heralded the release of World of Warcraft: Wrath of the Lich King. However, Arthas: Rise of the Lich King indicates that the grave had already been open for several years.

- When described in Arthas: Rise of the Lich King, Invincible was said to not be a warhorse- he would be a horse used in ceremony, as warhorses were of a different, larger breed. Yet, in his appearance in Wrath of the Lich King, his shear size, close to a full size draft horse (evidenced by great height and large girth) contradicts this. It is unlikely for a kingdom to use draft horses, traditionally used for labor, for ceremony, which would tradtionally see smaller breeds in use. Yet, Invincible is much, much larger than any other rideable horse in game, rather than the smaller size he was once described as having. This may be a retcon, magic, or may simply be Blizzard not thinking about the model size.
