Brandan had become lost again, but was close to the rest of the party. Every few seconds he created sparks with his soulblades to temporarily illuminate the darkness. Every time he did this, he changed his direction to where the orc had gone. Orcs are hardly light footed and left footprints that Brandan followed with haste.
Eventually catching up, he saw a single door with bright light shining through the cracks. No matter how much he pulled, he couldn't get the doors open. He heard whispers from behind the door, mentioning a vault of secrets. Through the cracks, he could see a leather binder, partly obscured by the vampires shoulder.
"Don't open it yet," Brandan called so that they hopefully would hear him, "You vampires are good with curses, right? Make sure there isn't a jinx on it."
Despite it's slightly racist undertone, what Brandan yelled was fairly correct. Hopefully they could hear him. Brandan also wondered why there was so many mystic doors in a mine.
