It is not unheard of for some combatants to make a life of fighting daily in the Pits. Linzara 'The Cyclops' is such a combatant.
The rules of the pits are not written anywhere and there is nothing that suggest that the combatants must outright challenge the Pit Lord when their trials are complete, but this is often the last mistake that fresh combatants make.
Lovingly referred to as 'The Cyclops' ever since she lost one eye from a strike by a Clawfoot's tail stinger. She used the very stinger to impale the beast in the same combat trial. Linzara is content to enter the Pits each day, emerging from her hideout deep in the decrepit depths of the pit tunnels. From here she makes short work of the enemies that emerge and puts on a fine show for the people of the Megopolis. After her three challenges are complete, she opts not to attempt the fourth and instead disappears back into the tunnels only to emerge the next day. Deep within depths of the pit tunnels thrives a secret city where only the most brutal survive. This is the place Linzara calls home.
