As a primordial god, Shiva is one of the few individuals who can pop down into the abyss at just about any time he wants, provided that Abaddon has not intentionally closed it off.
However, many of them do not know that they can do this, as Tehom's previous rulers maintained quite the strict closed door policy.
But even if they knew, most of them likely still wouldn't just pop by.
Unlike the previous rulers before him, Abaddon is fully synchronized with Tehom.
Meaning that as long as one is inside of his domain, he is effectively akin to the creator.
This place grants a monumental advantage for him, and a supreme disadvantage for anyone who comes in uninvited.
…But Shiva and the others were invited guests, so everything should be fine, right??
Shiva stepped through the portal he created high in the sky above Tehom.
To his surprise, he hadn't quite gotten close enough, and was surrounded by a cluster of floating planets.
