Those ancient gods had also let him leave his farewell message on the wall with a bull's head, although it seemed this one in particular wasn't too pleased with the decision to lock him up...
"Fuck you, Isis, Horus, and all the cowards unable to accept the new power; our race was and is doomed; the stories of Anubis are just stories; it's useless to go looking for our fellow humans in our universe. They're dead, and if they're not, sooner or later they'll find us again. You don't deserve the chance this earth has given you. I'll find you in hell, signed Bastoret."
Yes, indeed, this guy was very angry with his companions. It seemed that not all of them had been transformed into mummies of their own free will, but the message said a lot that Ikky didn't miss.
