Bravely, you step out and get Donnel's attention, then offer him the brown fizzwater.
He seems shocked to find you out of your room. You think you're getting better at telling the emotions of these people.
Though still shocked, to his credit Donnel is quick to get over his surprise. He stands tall and waves an arm towards the room, with some of the odd language of the Tall Ones. Several in white coats scurry into the hallway. It seems Donnel is in charge of at least this group of aliens.
Motioning the the vials of blood, you attempt to convey your confusion. Donnel doesn't seem to understand what you're asking of him, though he presses the vial into your hand.
Thinking hard, you put the vial back, step back, and start flapping your arms, kicking your leg back, and making several odd sounds. You get what you need by Donnels slack jaw and tilted head. Stopping suddenly and composing yourself, you again point to the vial and slack your jaw, tilting your head as well.
It takes Donnel a minute to comprehend, then his face lights up and he bares his teeth in the extra tall alien smile. They show too many teeth...
Donnel takes the vial and taps it, before leading you to a machine. He places the vial in the machine, and directs your attention to a slab of clearstone.
The odd human sigils you're starting to recognize start to appear. There are only four, this time, and there are no spaces between them like what you've seen before. Relaying to Donnel you are confused, he points at the screen, then at you, then at the blood.
You're still confused and mime him so. Scratching his chin, he takes a needle and stabs himself, drawing out quite a bit of blood. Using a clean vial he places it into the machine, and then points to the sigils and then at himself.
You think you understand something. The sigils this time are different, not in shape but in sequence. From the sigils a short while ago you see this sequence is vastly different. Perhaps they are magicing from your blood what makes you goblin?
If so... What purpose could they use this information for?
