The name 'COLAs' stood for Children of Limitless Ability and was given to the children of Tregarren College/Fenton Lodge. In Finding the Fox there were originally 109.

What joined Colas was their age being the same, unusual weather conditions when they were born and the fact that their mother's all died about 4 years after they were born (all of natural causes).

Not just children possessed these powers, for example Patrick Wood, Mrs Sartre and Tyrone Lewis had powers of their own, but they are adults and not classed as COLAs.
