Whirly

A whirly is a flying vehicle that is common in the vast underground realms throughout Ba'sAl and Trenn.
Designed by gnome inventors in partnership with their subterranean dwarven neighbors, these are often used by single or dual operators for aerial scouting missions, along with standard patrols throughout the vast underground.
Some whirlies have mounted ballistae attached for any hostile creatures they may encounter during flight.
