Cyclops
Stones for temples are taken from the south coast of Greece. Cyclops are working as slaves in the local quarries there. Eventhough they’re famous for being strong and simple minded, some of the one-eyes are clever enough to escape.
Unfortunately this leads to a gigantic problem for them: How to quickly hide somewhere with that enormous size?
Those who are unlucky and too tall, to fit into a wine barrel register into Hades “Underworld vs. Overworld – Overwhelming” Program.
Quiet often their life turns from slave to Underworld Soldier. A strong kind of career for even more stronger Creatures. And very strong opponents for you!
