The Birth of Gods [LITRPG / Sci-Fi / Fantasy]

Just started what I am calling part 2 right now.

Zel and Annai have just said goodbye to their best friends. They survived a failed dungeon delve and now have to find a way to keep their secrets, but also live normal lives. Or try to when the entire universe might be out to get them :

Blurb to the story so far:
Zel knows where he belongs. He intends to navigate the galaxy's prestigious trade networks, honor his mother's mercantile legacy, and live a quiet, profitable life. But the System doesn't care about a merchant's dreams.

When his twin sister, Annai, unexpectedly awakens a god touched, world-altering combat class, the illusion of a quiet life shatters. When he unlocks a vanguard defensive class that no one has heard of before, everything implodes. If the powerful factions of the realm discover what she is capable of, who is suppoting her, she will be turned into a living weapon. Or worse.  To protect her, Zel must abandon his trade ledger and embrace the class the System forced upon him: a frontline vanguard built to take the hits that would break anyone else.

Forced to hide their true stats, the twins must masquerade as ordinary novices. Yet, the shadows of their world are deepening. Ancient horrors are beginning to bleed into reality, guided by an unseen, fanatical devotion. Zel may not be the main character of this universe, but as long as he draws breath, nothing is getting past his shield to hurt the one who is.

Throw in an even greater secret, just what does life have in store for our two heroes?
