1099 The Fundamentals of Eternals 1

"I am the Aether Spirit of this palace, Vitae, and this is my counterpart, Mortem. We humbly welcome the Tomegamon King Anubesetesh into the Aether Palace of Vita Kingdom on behalf of King Draco, Queen Eva and Queen Shuangtian." 

Vitae paid extreme attention to etiquette as the spirit of the Aether palace, which made Anubesetesh nod. At least in terms of customs, the Evil Trio had managed to barely pass in this regard. He would have given them an even higher mark have if Mortem wasn't glaring at Anubesetesh the entire time as if she was just waiting for him to give her an excuse to act to her desire. 

However, he did not hold it against the hostile Aether apparition because he could easily tell this was its default nature, not anything specifically targeted at him. Mortem was formed from Riveting Night, so it was natural that her behavior was this way.
