Frozen Walkers

This is a monster i need so I have a reason to have penguin miniatures which have come in various marine sets. I just got an Australian Target pack of 10 buck sea creatures in a circular tube and the good thing is it has great eels, lobsters and 5 octopi! Just the right size for my 20mm mini games, very good freestanding sharks, dolphins maybe i should paint them pink and turn into earrings. Sea turtles kinda good in marine armies but might be giant turtle marine cities on an aquatic version of my incomplete mobile city wargame. Manya rays are cool but I need the right bases and maybe drill holes in them. Crabs always handy. Lots of seals too but I should use more selkies maybe make them a standard animal spirit changeling. But penguins man require some work.

These semi-mindless beings seem to have properties of undead and elemental animals. These vast bird like giants lumber relentlessly bringing disorder and terror and terrible weather. The are often driven by the wind on behalf of their frozen lord or by ice-mummy undead priests. Often roam alone or in packs in winter and cold lonely places to kill and murder. Larger ones may have multiple smaller ones as servants so a Guargantua will have a d4 Guardians and each Guardian has 2d4 Stalkers. Some may use close as guards or might use to funnel prey to them or scout a large area. Their haunted lonely foghorn-like honks can be heard on certain nights.

Mostly they serve evil cold elemental lords or might be summoned or guard a gateway in the frozen lands. Most cannot drop below certain altitudes or attitudes unless it is winter. Many serve the ice lich demigod who attacks mortals yearly from his floating glacial island. Unguided they will roam frozen places. They desire to kill warm-blooded life that drives them with anger
