A Kolgril is a type of fish found in the Purelake.[1]

Kolgril are said to be very lucky fish that can cure aching joints for a month after consuming one.  It is also claimed that an individual can predict when friends will visit after eating one by reading the shape of the clouds. One kolgril could provide two weeks worth of soup. [1]

Ishikk caught one for Maib, who has quite a fondness for them, on account of the finger aches Nu Ralik has sent her.[1]
