After the Giant war, several demigods were invited to become gods. And by several, I mean the 7 of the prophecy, Reyna, Nico, Rachel, and surprisingly, Will Solace. Many people were surprised that Will was invited, but the Gods had good reason that the demigods didn't know about. Will had been under an influence, like Octivian, but had resisted it and hadn't tried to wage war on the Romans. He had stayed loyal to the other demigods and hadn't gone all war crazy, like Octivian had.
(Coach hedge and Grover had also both been given immortality.)

Anyway, most of them excepted, except for Rachel. She didn't think she deserved it, to which the other demigods were shocked.

The original 12 Olympians knew that 22 Olympians was too many, so they started a new league of gods, called the Western Gods, as the demigods came from the west. Now, these new gods would have to be given there own respective domains, and so began the calming.

Percy became the God of the time between high tide and low tide, the so-called 'bridge time' since he was a bridge between the Greeks and the Romans. He also became the God of sea animals and the sea bed. But his most powerful aspect was loyalty. His children would have intense loyalty to their families and friends, and have all the 'powers' of children of Poseidon.

Jason became the god of dawn and dusk, the bridge between night and day, as he too was a bridge between the Greeks and Romans. He was the god of tempests, after his horse, and the god of calm winds. He often helped transport demigods safely on quests.

Leo became the god of strong souls, as he had lost so much, but still had a strong soul. This meant he blessed certain people with having strong souls, and his children had them, too. He also became the god of fire users, dragons (mechanical and non), and laughter.

Frank became the god of shape shifters, meaning his children were shape shifters and he could bless other people to be so. He also became the god of orders, such as legion, advance! And so on. (This meant his children were amazing leaders and could give orders very well. Some of his children became war generals, and they resembled George Washington, Ulysses S Grant, and so on.)

Annabeth became the goddess of architecture, and her children went on to be amazing architects and designers. She was the goddess of strategy, whether battle strategy or not, and loyalty as she never gave while looking for Percy.

Hazel was the goddess of precious metals (even though she hated the fact that her children could raise them.) time travel only into the past and underground spaces. Pluto happily handed over the underground space duties to her, but he still was in control of the underworld.

Piper became the goddess of compassion, and family love. (Like sisterly love, motherly love, etc.) She became the goddess of persuasion, as Aphrodite handed that over to her. She also was the goddess of singing, not like Aollo, but with warmer, more meaningful songs.

Reyna became a maiden goddess. She was the goddess of dogs (mechanical and non), and shared strategy with Annabeth. She also became the goddess of instincts, as her instincts were so sharp. This meant her children had very good instincts and she could bless people to have them, too.

Nico was the god of shadows and shadow travel. He was also the god of opposites, as he and Will were opposites. But the one thing he was most passionate about was rebirth. If you wanted to be reborn, you would have to go to him. He would search he earth to see if there was anyone alive that still longed for them. If two people approached him and wanted to meet each other in rebirth, he would bend the will of the fates to allow them to marry or fall in love.

And Will also became the god of opposites. He was the god of the sun, as Apollo was banned from Olympus, the god of bravery, and the god of balance. If something was unbalanced in the world, he would set out to rebalance it.

So these were the 'powers' of the gods. But the boys of the 7  were given a 'joke' as one of their powers. But they took it quite seriously. (😜)

Percy was the god of blue food and sass.
Jason was the god of bricks and hot gas
Leo was the god of tofu burgers, jokes, and shared sass with Percy.
Frank was the god of iguanas and Chinese hand cuffs
