Myriad

An enormous, intelligent, arrogant swarm of cranium rats, encountered in Central Dolmingdran. Myriad helped the party slay the Sovereign, and in exchange was smuggled past the dwarves out of the city.

Myriad disappeared several days later, taking The Mindwitness with them.

Miri
A swarm of cranium rats that used to be part of Myriad. Speaks telepathically and is not very bright.

Myriad used smaller swarms to scout Dolmingdran. Each called itself Miri because it could not remember the full name "Myriad". The party met a Miri in Dolmingdran, but it's not known if this Miri is comprised of the same rats.

Left after Myriad disappeared in Dural somewhere, likely as a parting gift to the party.

Friends with Quad.
