[RPG] Does “each creature” in the Mumthe Lord’s Blinding Dust Legendary Action include allies

actionsdnd-5emonsters

I have been reading up on monsters in the Monster Manual, and I have a question about the mummy lord.

Legendary Actions

[…]

Blinding dust: Blinding dust and sand swirls magically around the mummy lord. Each creature within 5 feet of the mummy lord must succeed on a DC 16 Constitution saving throw or be blinded until the end of the creature's next turn.

Here is my question:

When it says "each creature", does that include allies or just the enemies to the mummy lord?

Sorry if this is a silly question I just think it isn't too clear. Thanks!

"Each creature" means every creature in that radius.

If the text meant only specific creatures, it would say so. For example, picking randomly from spells, Aura of Life states,

Each nonhostile creature in the aura (including you) has resistance to necrotic damage, and its hit point maximum can't be reduced.

Since the Mummy's action doesn't specify anything about the creatures, it means all of them.
