It was an odd fog, the black fog of one's mind. Usually one could see anything, if they merely asked. This mind was tainted. Spoiled. The more one thought of it, the more rotten it became. Smelling of fowl death and the icy cold of despair. It wasn't the right, this fog. It didn't belong here. It was put here, not created.
Having been in the minds of Potter, his mother, Black, and Pettigrew, Snape was able to tell this mind was not right. Lupin had something when he asked Severus to come. He scowled in concentration. This was not right. He needed it to be right. He could just Obliviate her, of course, but Lupin had some reason for wanting him to do it, didn't he?
Whispers of various phrases, sentences, entire paragraphs and singular words occasionally drifted through the floating mud... unfortunately for Severus, they were entirely in elvish. However, some could be heard quite clear.
Dolle naa lost
Hearing the elvish, Severus cocked his head. He registered it in his memory, though he did not know the translation. He was almost certain that Tonks nor her subconscious would know it either.
It said in a loud, crystal clear voice. It also attempted to throw Severus out of Tonk's mind.
Feeling distinctly unwanted, Severus agreed to go along with the wave out of her head. He had questions. Questions that needed answering.
Snape reappeared in the black, foggy abyss. "Tina?" he queried politely.
"Huh? Oh, hello. My name is Carl. How do you do?" It grunted and snarled and snapped in a rather vile way, however it was only his way of communicating. In elvish, he was actually very polite and civil.
Knobby translated for Severus. Snape told him what new to say.
"I am Knobby, and this is my friend Severus," Knobby told him. "I'm afraid I can't quite place you in a species for my friend. Perhaps you could simply tell me...?"
The thing sneezed- which was a large shout and a push of violent wind outwards. "I'm afraid I must be rather allergic to your friend there-- terribly sorry." He screamed and snapped politely. "I am a dark elf, of the ecto-kind. Fifth class tormentor. Rather like a 2nd cousin of a dementor, once removed if he needs any dumbing down... which by the looks of it, I'd say he would. Care for a memory? They're rather tasty. Here!" He ripped out a chunk of something from the darkness (which in the other thread would have made Tonks jerk slightly.) and handed it to the little house elf.
The House Elf wrinkled his nose delicately. "No, thank you. Trying to quit, you know." He handed back the strand and did not translate. "I'm afraid I have never heard of any 'ecto-kind' of anything. Could you maybe be mistaken about your own race? I am certain my own mother would have told me about any sort of cousin." He tried to make a placating gesture.
"Oh, I know they don't like to talk about us-- but you have heard of us. Possessions, incubi, succubi, "Mr. Sandman," "Popobawa," "Pazuzu." Plus we're rather difficult to pay, being of the ethereal and unable to touch anything tangible like money-- but our credit accounts are astonding."
"Are they really?" Knobby queried. "What precisely can you do with your astounding credit account, anyway? I mean, if you can't touch anything tangible, what would you buy? Why do you do this? It can't be fun for its own sake... Why are you doing this?" He furrowed his House Elfish brow. "And I really don't think I've heard of you fellows..."
"Well, for starters, you are nothing but a simple little slave species. I wouldn't expect you to know of me, so I am not offended by your ignorance." He stopped to sneeze again. "However, the money problem has always been, well, a bit of a problem. However, as long as I keep doing this, it keeps the missus happy, and well, one must keep the missus happy."
Knobby translated for Severus. Snape indicated his next question. "My friend is interested in your missus," he said shortly, but not impolitely.
