If everything goes suddenly dark...try using a light. Candles and lanterns are readily available for purchase from Nom, Sol or Jim the Peddler, but it is always best to bring some spares along. - Calidon
Fix-it Floyd has gone to work on the Mob Factory...
The place that produces mobs all around Avatar has been refurbished recently. After a catastrophic incident with a disobedient Collosus, Fix-it Floyd took the opportunity to slightly Revise the factory, though for an old-timer such as him that probably meant something as simple as finally installing doors.
See if you can help Floyd to get the production back on schedule. This quest is for players up to and including level 11. If some players cannot access this quest, the problem is psychological, not mechanical. See HELP MOB FACTORY for more information.
