Officially labeled as Cell Block 5 on the complex's schematics, the lowest level of the Hvalkatar prison is known by a more dubious name – the GraveRing. Named after the fighting arena located in the middle of this level, it is here that the most dangerous inmates are housed, and where they are forced to fight for the amusement of the brutal Highwarden Slogg and his honored guests. Horrible circumstance often foster strange alliances, and some of the prisoners of the GraveRing find themselves bonding together to survive the brutal fights. Taking their name from the cellblock itself, the group known as GraveRing has a plan to turn the tables on the T.U.5.C.C. Gravekeepers who guard the exits from this cell block. If they can get past them, they can get into the rest of the complex and find a way to escape with their lives, and with some of the secrets that are going on at the dreaded Hvalkatar.
