The talking horse is Xanthus
You are the Immortal Horse XANTHUS. You can talk! You tell Achilles you will bring him back this time - but that the hour of his death is drawing near. But it won't be the horses' fault, any more than it was your fault when Patroclus fell. He was killed by the son of Leto, who let Hector have the glory. Achilles too is destined to fall in battle to a god and a man ...[at this point the Furies strike you dumb. You'll have to neigh like other horses from now on]

Xanthus and Balius, the immortal horses
