- Hallow Clan resides on the roof of the mall building
- These cats are seen as haughty and overtly religious; they consider themselves the closest and most loyal to Star Clan
- The mall is quiet overgrown, with a few tough plants - such as bushes and grasses - making their home on the roof of the building
- Hallow Clan uses the mall ventilation system to maneuver through and exit the building
- This clan relies on rainwater gathering in a meticulously kept rain barrel for water, or whatever puddles they can find on the roof; very rarely do they go to Echo Clan for water
- Cats in this clan tend to be named after anything related to the sky (or close-enough to it)
- Den Locations:
- Leader’s Den: a utility shed near the broken staircase at the center of the structure
- Medicine Den: A large bush growing out of a busted A/C unit near the leader’s den, which - after years of meticulous disassembling, is also part of the den
- The A/C unit is the storage for herbs, while the underside of the bush has been formed to give plenty of sleeping space
- Warrior’s Den: There is no official warrior’s den in Hallow Clan. Warriors sleep in the various vents found along the roof
- Apprentice’s Den: A reinforced rain tarp and row of about five empty barrels, all turned on their side and kept from rolling by cinder blocks, make up the apprentice’s den
- Is found off to the right of the leader’s den
- Elder’s Den: The elder’s live in the broken stairwell next to the leader’s den
- Nursery: A patch of thorn bushes, near the apprentice’s den, through careful forming over the years, makes up the nursery
