Threat

Not many Divine Gods had actually heard about Nial before. 

The Undying, Dilan Cier, was a little different because he actually fought against the weakest Ancients and Primordials when he was not even an actual God yet. Dilan had been strong enough to fight Gods with his overwhelming combat power and the Origin Ability called 'Undying'. 

He was not someone, who died that easily, not actually at least. His body was often torn apart or even eradicated to the finest atoms. However, even then, Dilan always survived. Undying was an Origin ability that was simply too powerful for ordinary beings to possess, yet, Dilan was in possession of this Origin ability, and he could make use of it properly!
