Eternus [The God of Time]

[MORTAL x IMMORTAL] After Prince Eric's father dies, Eric is betrayed by his uncle Henry, who usurps the throne and banishes Eric and his loyal courtiers to the woods. The Kingdom of Thames falls under Henry's cruel rule. To reclaim his throne, Eric turns to the generational priest, who advises him to seek the aid of Eternus, the God of Time. Summoning Eternus, Eric receives a golden pot filled with magic sand that can freeze time for a total of 30 minutes, used in intervals. The deity also agrees to assist Eric in human form but will vanish once the sand is depleted. But time isn't free? What'll Eternus ask for in return?
