Inkmatas revival concept:
"But the ink refused to die"; Inkmatas wakes up in her coffin, teleports out using a new "magic", then contacts collector. He discovers that she's in sort of a half-alive state, her soul is partially separated from her body, meaning she can do ghost stuff without being dead. The only drawback is that she can BARELY use inkstone. She can make a few sparks but that's pretty much it. Collector theorizes that the soul part was caused by whatever energy inkmatas was exposed to when she died.
