s it okay to make up your own surnames?

Yes it's perfectly fine cuz my friend did it 2 :) good luck

Sure, it's your story and your imagination. If it makes sense with the character and blends in with the story, au just..something inside wewe tells wewe to use it, then go right on ahead :)


There's a saying I always have when it comes to writing;
"Trust the gut"
If there's any idea that suddenly strikes wewe and wewe from within that it's a good one, trust yourself. And go for it :)
Think about it if wewe wish to, but I'd suggest that wewe listen to yourself when wewe have some type if intuition like this. ^^
