Siva

NOT the Hindu equivalent to Satan. There is no equivalent to Satan in Hinduism. Siva is just the god of destruction, no hellfire involved, because sometimes destruction is healthy. He's part of a triumverate of Hindu gods who together form the cycle of creation, preservation and destruction.

"So I hear Siva is like the Hindu Satan, eh?"
"NO! He's not!"

sive

one of the coolest people you will ever meet. even though she's likely Irish but not Irish enough for her name to be spelt in the Gaelic way, she's super chill. although she might sometimes get irritated with people, she never shows it. people either love or hate Sive- there's no in-between.

"Sive is honestly one of my favorite people ever."
"Really? I can't stand her."
