Gisa and Geralf
Gisa and Geralf are two rival necromancers (sister and brother, respectively) from Innistrad, both quite insane. Geralf is Blue- aligned "stitcher", stitching together new zombie designs from various body parts. Gisa is Black- aligned, resurrecting the dead directly from their graves.
The siblings were scions of a noble family and distant relatives of the current Lunarch. They were banished from Thraben in a hushed scandal and have since moved to the Moorland, where they wage war against one another by raising armies of undead. Their battles have prompted many of the Moorland's inhabitants to move to the Nearheath, leaving the area even more desolate than before. Now, marauding ghouls range freely through the moors, lost playthings in the mad, epic battles of Gisa and Geralf.
Geralf had taken over Trostad, most likely massacring the inhabitants that didn't flee. He is known to have grand ambitions, though his sister is far less formal and driven by her whims. For example, Gisa has attacked Trostad in the past simply to best her brother.
Later on the two would plan on waging a war against one another. Geralf had tried to set formal rules for the engagement such as:
- requiring the Ghouls to have three or more limbs,
- no summonings could occur mid engagement,
- it had to be a 'straight up' engagement without strategies such as surprise attacks or flanking.
Gisa however would have none of this and considered all was free game, frequently defying Geralf's rules if only to infuriate her brother. The engagement was called off when Geralf decided to invade Thraben, he invited Gisa along, and the two broke the outer wall of the city before being pushed back. Geralf would sneak into the city before the attack so that he may kill Mikaeus, and later he met up with Liliana, who shortly thereafter brought Mikaeus back as a zombie. Gisa was thus left with tending to the siege, having gained control of Geralf's Skaabs along with her own conventional undead.
Geralf is also the creator and master of the zombie Grimgrin, corpse-born. He said that he named such in mockery of his sister's face.
