Blood of the Vampire
At last, it was my turn to enter the portal. I was used to the feeling by now. A purple light enveloped me gently, and when I opened my eyes again, I found myself in a somewhat...unusual environment. The sky was purple, and it was raining. Lightning struck down from above, with loud thunders to accompany them.
But perhaps most bizarre of all was the structure in front of me - a massive, medieval-style castle, which I could only make out the silhouette of within this howling thunderstorm. Occasionally, I would get a clear look at the castle's true form - whenever the lightning bolts struck down, that is. Nevertheless, seeing as how there was nothing but water behind me with no visible land in sight for a good kilometers at the very least, I had no choice but to head inside this grand yet horrifying architecture.
