The Penguins are a race of sentient birds. They planned to take over Gielinor before the Third age, but when Zamorak won the God Wars, they plotted to take his power.
All the penguins use a mysterious iceberg as their base. It is in uncharted waters, so it cannot be easily found.
They have been plotting for millenniums, and still no success. They have spies everywhere, pinpointing weaknesses of the Zamorakians.
Their must recent plan was to use a death ray to destroy Tutorial Island, but they have been delayed by a couple of days due to technical problems. They are currently pointing the death ray at Tutorial Island.
