From the Diary of The Mad Fool Zuglarning:
Experimental subject 56-142A:
Initial grafting of replacement limb successful, and rejection was successfully prevented. Unfortunately, the virus I used to suppress his immune response also caused him to gain four times his weight in tumor cells within six days. Results promising.
On a personal note, subject 56-142A has repeatedly requested me to let him die. Since he has been so insistent upon the matter, I have decided to be reasonable and fulfilled his request. After all, seeing as how he lacks three of his five senses and can no longer move, his usefulness to me as a test subject is somewhat limited in any case.
On to less important matters. The fortress had a...visitor yesterday. A creature of the void, and they are every bit as impolite as I remember them. Fascinatingly, the creature used its long, powerful arms to accelerate its blows, permitting it to deal grievous injury even with a shoe. Unfortunately, learning its properties in Euclidean space required the sacrifice of several vessels. An unfortunate necessity, but the trade-off will probably be worth it. We now have its body, and I have put in a request to examine it. We may yet learn much from this creature's remains.
In the meanwhile, I have begun preparing subjects 56-142B and 15-142C for the same treatment, so as to confirm my results. I wonder if we couldn't tap the uncontrolled tumor growth as a food source....
