Roland and his horse arrive at a deserted village, Eluria, where they encounter a feral dog bearing a cross-shaped spot in its fur attempting to eat a dead body.

Roland slowly discovers the Sisters are actually vampires, who bring stray survivors back to their "hospital" only to feed on them once they've recovered.

She sneaks a dose of a powerful herb to Roland, which counteracts the weakening potions, and he slowly regains his strength until they are ready to escape.

The sight of gushing blood incites the Sisters into a feeding frenzy, allowing the mutant to escape and Roland to retain his medallion.

Their leader, Great Sister Mary, soon catches up with them, but is attacked and killed by the same cross-bearing dog Roland first encountered.

The vampires and Low Men receive Mia/Susannah shortly afterward in the Arc 16 Experimental Station, where Sayre threatens Dr. Scowther.
