Cid will request that Rialynn bring him a Cockatrice egg. Be sure not to let it get cold, as that will cause the egg to not hatch. He does not deign to explain why he needs the egg. It is probably not to domesticate and use to petrify pesky Heroes who keep coming to his office.

When Rialynn returns with the egg, Cid will award her with the Pirate job. You can log or handwave this quest at your convenience. Ira has been given the same quest.
