When Gaia got the message that her children might be facing the Primal God king of the Hindu Realm, Lord Shiva. She immediately left her domain and made haste to the Mountain without even thinking.
She flew at her highest speed and hoped that her children took her advice and not engage with that guy.
She knew how dangerous Shiva was, he is Primal god and a God king, which even boast his powers further.
Not to mention his annoying little demons that he uses in his fights making everyone steer clear of him.
"What does he even want. I thought he left for his domain after they brought him here to meet Adamantheia for a cure to his injuries he received in fighting a sibling of Lucifer. And I don't remember Chronos making arrangements with him, so why is he still here and also attacking my children?"
