Why would you be hated for asking questions? They are valid. Though I am upset that you revealed a bit of the story XD.
Voidspawn are creations of the void itself, that will be explained as the story goes on.
The attack was the first one to happen in 19 years, that will also be explained.
No they had not, Lethe was convinced it was just the one attack and then it was over, until the second attack.
The other villagers did not need to escape, the voidspawn were after Corinne.
What Tobias had planned for that night, sadly, does not matter as the attack interrupted it.
Aelmourn isn't cursed, Tobias hunts there normally and he had a nice surprise set up for Corinne.
Yes, Lethe IS badass

I don't know about other people joining, it's not my decision as I am just the writer. I know that we have Strawberry on basic art, Dragoncookie does inking and backgrounds and I do writing and website/advertisement stuff, though a lot of the website stuff is split XD. Not sure if we need another person or what you could really do that isn't already being taken care of.
