The Skos are part of the Stormwood Army which is in charge of the Forest defense and protection.
They alert others when danger is near thanks to their loud scream; they make perfect alarms.
Small and wood-like they easily hide in trees. Blind, they have amazing hearing and smell senses. They instantly detect when there's a problem.
More recently, they are willing to go among humans to help them. They alert them when there's a danger: they are amazing House Guardians!
(Skos in the plural)
name inspired by the English word scout.
