The mystery of Golden temple!

So just let me get this straight.

- The Ravana Helm (my main goal in this whole yippa-yappa) is DROPPED from the all Ravana Bosses. T/F
- The Ravana Boss is in an altar (like Pap?) and can be fought solo/party within an amount of time (how long?). You need 5 Sun Orbs to enter the map that leads to Ravana Boss. T/F
- The Sun Orbs are semi-rare ETC drops from all the monsters inside the MiniDungeons, untradeable. T/F
- The MiniDungeons are accessible with a Golden Ticket. There are 2 ways to obtain these tickets: one per day from Mr. Yoo and purchase from CS. T/F
- This is new content, not new event. T/F

I have a few questions:
1. How many do the Golden Orbs stack into? Can I hold more than 5 at a time?
2. Confirmation on 2 of my assumptions: Ravana Helm is the same no matter which Ravana Boss drops it; and the Sun Orb drops from all mobs, regardless of your level.
3. Is this how the Golden Ticket works: Enter a portal -> choose an option for an MD -> get warped inside and lose a Golden Ticket in the process?

Thank you.
