Mane six are unwilling villains. It's complicated, and you'll just have to join up to find out exactly. Half the story is to rescue them. The last RP stalled on some good plot points which will happen again of course. Your character is fine Tang, if you can explain the origin.
And unless you want my writing to suck major bull you know what, don't tell me to write in third. I can only put out believable characters in first. I can't get into their heads otherwise. It's just the way I write. It really doesn't affect you, so I dunno why you'd have issues with that. I don't like when people RP in third, but I think it's not nice to tell people how to write lol. Let's just not talk about that, please.
I've watched all of WITCH too. Great show, but it was all resolved by the end. I'd you wanna go ahead and make a RP on it, I'd join.
