Hesed of the Black Anvil Guild:
Because Dr. Chaos rubbed Nornil the wrong way, that's why! Anyway, go ask Verna for details on Nornil and Spiculas on the Isle of Souls and all that. I mean, the situation was technically caused by a mad Dwarven scientist, but it's also connected to the birth of the Kamael race. I can't really divulge the details.
Whoa, been talking too long. Anyway, take this vaccine box to the Seal Watchman guarding Yin, will ya? Now, don't frown like that. You were helping us already, a little more couldn't hurt. I'll be sure to pay you for your troubles when you get back.
