This loyalty was exploited in 2E 582 when constellations fell from the skies above Craglorn and took on mortal forms known as the Celestials. One of them, known as The Warrior, used divine powers to invoke great warriors of the past. However, he did so at the command of The Serpent, and thus Tarish-Zi and the Anka-Ra were summoned forward in time.
Unbeknownst to The Serpent, The Warrior also summoned Titus Valerius, a powerful Nedic warrior who would act as his champion against Tarish-Zi and his army. Titus was aided by the Vestige. They both entered Tarish-Zi's Tomb and slayed him, ending his effort in laying siege to Craglorn and freeing The Warrior from The Serpent's corruption.
