This is the lore behind this and some free Darren lore for you:

Darren was human at one point, a simple man who once went though hell and back just for his family until one day he saw a flyer saying "Help Wanted" with a address on a slip of paper, he was looking for work at the time so he takes it. after following the directions on the back of the slip he walks into a store then promptly gets knocked out, he wakes and looks around at the tiled walls of a cell with a 2 way window, two scientist stood behind it, he looks down and see's himself not in his normal clothing he was in a hospital gown and tied down to a bed, he starts tugging at the restraints suddenly a females voice comes from the speaker in the room "Please remain still." so he did until he felt something under his skin.

Its been a year since he was injected with THE TAR, he hasn't been the same since, the doctors and scientist cant take blood samples anymore, they cant even take skin samples, Darren's skin has became solid instead of goo like expected, his hair has grown in a alarming rate and he can control how much is there or not, the scientist take notes on notes.

The last LOG of a scientist was found 3 floors down it says: Its been 345 days, 20 doctor's dead, 50 scientists dead, 5 injured severally, the subject is breaking though the glass if anyone sees this, DO NOT INGAGE DURING HOSTILE STATE. that was the last LOG ever recorded, You've read the files on this case but never seen the aftermath of it, the dry blood, the Handlers and scientist and doctors you were sickened by this sight, you noticed a picture.
