Hi,
I destroyed the big blood stone while being in a fight with some dogs to its left. Using a white Tenebrium-Sword on one of my main chars. It took some hits and with its end all the enemies vanished. Zixzax showed up, thanked me and I went back to Homestead. Story / Portals kept opening from now on.
Thats how I did it.

There are more than 4 bloodstones out there I believe. Sadly I only found a german guide to find them all. Maybe by collecting and using more you ll be able to open it.
