Tragedy! Werecamel early in the second year--two dwarves and the entire herd of grazing animals outside are slaughtered before they can escape.
Within the stone walls of the fortress hospital, three more dwarves languish in the aftermath of the attack... and feel something changing inside them.
The fortress descends into chaos. Three enraged, rampaging beasts break down the door of the containment area, then proceed to slaughter and convert all in their path. Workshops are trashed and hauled items flung aside in the population's headlong flight to safety. Four dwarves die where they stand, barely putting up a fight. Two more rise later as creatures of the night. The rest are picked off one by one as they scramble for the nearest exit. 12 dwarves lie dead or dying, and 4 more have been infected.
The local militia and visiting warriors make a brave final stand in the beer-swamped halls of the great tavern, but are sadly overwhelmed by the mass of werecreatures clamouring for noble dwarf blood. The warriors with silver weapons manage to end the curse for 3 werecamels, but are slaughtered in the face of their inhuman (indwarven?) strength.
A solitary dwarf is still alive--he was asleep in his bedroom, and did not hear the noise of battle outside. Perhaps he can rebuild this fortress single-handedly.
