Once Eldros had been risen from the dead by the Great Tree, he had received the order to kill Zaroth.
But something deep within his soul resisted. The slave contract still bound him—acting against his master was out of the question. And even if the contract had never existed, he still wouldn't have obeyed that command.
Yes, the Great Tree had brought him back, but Eldros' soul remained tethered to Zaroth's. He was an undead creature not a beast, following the commands of a Beast Master.
Something that should've been impossible. Zaroth was a Beast Master, not a Necromancer. And yet, due to the strangeness of the situation, the impossible had become reality.
That also meant after the Great Tree had perished Eldros did not. His soul was feeding off Zaroth's and his mana core, resulting in him still standing.
With silent steps he approached the fallen body of the Dullahan, then with no shame he put his hands on the being's body and stripped off its armour.
