Well I talked to the girl and showed her the Pokémon she wanted to see. She gave me a dark core? And told me to find a shrine and dark matter. Or did she give me dark matter and said to find the dark core? If so where is the dark core lol
I think she gave the Dark Core. Either way, to get the other item, go back to that Bladestar underground Lab that you stucked with Erin (The one where you have to find notes to mix stuffs), I'm not sure if you can still go back in V12, but if you mix stuffs in a specific order (there's a thread about it somewhere in the forum), you will get the Dark Matter.
