GOODBYES ARE ALWAYS THE HARDEST!
Alba and Mahina wouldn't have desired to leave earth but the child both conceived on earth has so much power in him that's unimaginable and like Axel said when the earth perceived strange elements it's bound to react to it. And I believe also, from what we were thought back at my planet about the planet earth is that it's not able to accommodate two suns. Kiran Mahina's son has his father's power even if he also has his mother's power which is suppressed by the presence of Alba's power---"
Axel got tired of Veer's detailed explanation and yelled:
"Oi I have had it with you two. In essence what Veer is trying to say is that Alba and Mahina had to leave because the earth can't contain their power. Leaving wouldn't have been a problem if Kiran wasn't marked after birth by an estrange betrothed. It became a problem for the two because they can't ascend with him… he can only ascend after he finds and falls in love with his betrothed"
